Thank you for your response.

I understand your point, but I want to emphasize that I have been extremely careful with my backup. I have cross-verified my 12-word seed phrase multiple times from the Mycelium iOS app before the issue started, and it is exactly what I have been using for recovery attempts.

Given that the correct public address still shows the accurate balance when I import it into Trezor Suite, I believe the seed phrase is intact — but the issue seems to be with the derivation path or how Mycelium generated the wallet internally.

Is there any way I can determine the exact derivation path used by Mycelium iOS around the time I created the wallet (approximately five years ago)? This would greatly help me locate the correct address using a tool like Sparrow Wallet. Have you heard of Sparrow wallet and what do you think about it.

I’m committed to recovering access, and I’d appreciate any specific technical guidance you can provide.

Best regards, 

Thanks for your follow up response. I did try most of your suggestions for trouble shooting this problem, below is what I tried and found out.

First off, the Mycelium iOS app where I have the correct account balance and transaction history hasn't been able to send or receive BTC for some years now but I started experiencing these challenges 7 months ago. However, on the 13th of every month Mycelium apps pops up a notification to verify the account where I need to enter 12 words master seed after inputting these words, it tells me the seed doesn't match the wallet despite been sure of the master seed as I still have the wallet and I tried to back up again just to confirm if I have the right phrases which corresponds with the phrase I have had since I opened the wallet.

Secondly, I import these master seeds into the Mycelium Android wallet but shows a different/wrong account balance and transaction history of 5 years ago. I only have one account on Mycelium iOS wallet but still tried to use the "Add Accounts" on Mycelium Android wallet but those revealed O BTC and no transaction history.

It's worthy to note that Mycelium iOS wallet only provide public address but does not export master seeds or private keys and no where on the wallet could you know which derivation pathway but I know for sure it is a Legacy account because the BTC address starts with "1P1S". So I went back to I check for the derivation pathway for the account I imported into the Mycelium Android wallet with the low account balance and transaction history from 5 years ago. I discovered the Legacy(P2PKH) account on there had "1GPG" address and derivation pathway of m/44'/0'/0'/0/15.

Subsequently, I have tried importing this seeds into Electrum, with the BIP39 and detected derivation pathway and gave me the same account balance and transaction history I got on Mycelium Android wallet. I tried playing and trying different pathways but they all brough 0 balance.

I also tried to scan and link my pub address on Trezor Suite Lite and that gave me the accurate account balance and transaction history as I have on Mycelium iOS wallet but it's more of a watch only wallet or a wallet to track your BTC.

At this point I have tried all I could but do not know what else to try and hoping I can find a solution to these challenges.

Once again, thanks for your guidance and assistance.

You are right and do not think they are going to be doing anything about it. It has taken too long for the management to fix the "technical issues"

Once again, I appreciate your kind suggestion. When recovering via Electrum I used the detect account option which said it was a bip32 m/44h/0h/0h derivation pathway and since I only have one account with Mycelium. However, it still displays the wrong account balance and history of 5years ago.

Thank you once again for your response. I tried importing on my electrum and did the detecting account after entering the 12 master seed and it confirmed it was for the BIP39 but I still got the same result.

This technical glitch has been reported by some customers to have been happening for some years back but I actually started experiencing it early this year. This is the 7th month and they haven't rolled out a new updated version yet. How long will that take, I'm not sure what to think anymore. I just feel I have been unfortunate to be caught in this dilemma as I can't access my funds anymore which is quite frustrating.

Once again, thank you. I will be open to trying more options if there are some.

Thank you so much for your response. I only have one account, I tried it on different wallet including the Mycelium Android app and they keep showing the same balance different from what I have on the iOS app. I have tried everything possible, Mycelium will tell you your funds are safe but you can't access your funds with the seed you were given. This is so frustrating.

I only have one bitcoin wallet and account and it is with Mycelium iOS wallet, where I can see my correct balance. However, I can't send or receive funds on it due to some technical glitch reported by Mycelium. I tried importing my seeds into the Mycelium, blue wallet and Electrum but shows a very low balance which is different from what I have on iOS Mycelium wallet.

I tried both but it keeps showing the wrong balance and transaction history of 5 years ago even before I started using the account.

Here is one of the emails and summary I sent to support@mycelium.com concerning the issue on Mycelium wallet and some of the possible solutions I tried, anyone with similar problems or solution should please share:

Hello

I am writing to express my deep frustration and disappointment regarding the ongoing issue with my Mycelium iOS wallet, which has remained unresolved for over six(6) months.

Every 13th of the month, the app prompts me to verify my account using my 12-word master seed phrase. I have entered the correct backup phrase—separated by spaces—as required. Despite this, the app repeatedly states that the phrase “does not match this wallet.” I still have access to the account, which confirms that the seed phrase I’m using is correct.

Additionally, when I attempt to send funds, the transaction ID returns an “Invalid BTC Transaction” message on the blockchain. This suggests a serious issue, either with access integrity or wallet functionality.

More alarmingly, when I use the recovery seed on the Android version of your app, it displays transactions from four years ago and a significantly different account balance—completely inconsistent with my current account.

All evidence points to a serious breach or malfunction on your end. At this point, I no longer believe this is a technical glitch. It appears I have been locked out of my wallet, and I have reason to believe that my funds have been misappropriated.

Let me be clear: I will not allow this matter to be brushed aside. My legal representatives are already reviewing the situation, and your organization will be hearing from them shortly. I intend to pursue this until I recover my funds in full—and more if necessary.

The lack of support and transparency from your customer service team is unacceptable. I urge you to take this seriously and respond promptly with a resolution.
Sincerely,

Here is some thread of emails I have sent to support@mycelium.com with minimal response with the situation I have been facing with mycelium account for over 4 months. I tried reaching them they replied to some of my initial message after some month and for the past two months they haven't replied my messages. Maybe it is time to take some legal action against this fraud company.

Hello,

Hello Mycelium Support Team,

Thanks for your response. I am writing to express my deep frustration regarding an ongoing issue with my Mycelium iOS wallet.

I am currently unable to make Bitcoin transaction on the iOS wallet. In an effort to recover access, I attempted to import my wallet into the Mycelium Android app using my master seed. However, the balance displayed there is significantly different from my actual balance and only reflects transaction history from over four years ago. Just to let you know I only have one account on the wallet so I do not understand why I have the actual balance on the iOs wallet and have about $55 on the Android wallet which is way lower than what I have.

I chose Mycelium because I trusted your platform’s reliability and security. Unfortunately, this experience has left me feeling abandoned and extremely concerned, especially as I have pressing financial matters to attend to.

I urge you to please escalate this matter and assist me in resolving it as soon as possible. Access to my funds is critical, and I would greatly appreciate timely support and clear guidance on how to proceed.

In addition, what exactly is the "technical issue" and how soon do you think this issue will be resolved as it's been almost a year now. A lot of my transactions is tied to this wallet.

Thank you for your attention to this matter. I look forward to your prompt response

Hello,

Currently, we support only 2 types of addresses on IOS, P2SH (Segwit compatible), which start with the number 3, and P2PKH (Legacy), which begin with 1. If you select one of those address types and send your bitcoins there, it will work. However, we highly recommend using Mycelium Wallet on Android as we are currently experiencing some technical issues with the IOS version, and the Android version generally works much better. Apologies for any inconvenience.

Best regards,
Mycelium Team

Hello,

I'm still awaiting a response on how to retrieve my funds. This is unfair as you have been ignoring my messages. I do not understand why your team have decided to do this on your customers. I leave with regrets everyday that I used your wallet for my bitcoins.

Hello Mycelium Support Team,

I am writing to express my deep concern regarding the unresolved issue I’ve been experiencing with the Mycelium app for over four months now. Despite multiple attempts and following all the troubleshooting steps provided by your team, the issue remains unresolved.

The last correspondence I received from your support team stated:
"Hello,
Don’t worry, your funds are not lost. Can you please provide me with some details such as the version of Mycelium Wallet that you are using, as well as the make, model, and OS of your Android phone? Thanks!"

In response, I promptly provided the requested information:
iOS Device:
• Model: iPhone 11
• iOS Version: 16.3.1
• Mycelium Wallet Version: v38
Android Device:
• Model: Samsung Z Fold3 5G
• Android OS Version: 15
• Mycelium Wallet Version: 3.18.2.0

Since then, I have not received any further communication or support, and the problem persists. As a customer who entrusted your platform with my funds, this prolonged delay and lack of follow-up are both frustrating and deeply disappointing.

Please treat this matter with urgency and provide a definitive resolution or next steps. I am eager to have this resolved as soon as possible.
