No, I have 1 ledger nano device I used to set up the Bitcoin 2 account on the live app on my phone but that nano ledger device wasn't being recognized by the live app when trying to transfer, so I attempted to restore the nano via the 24 PW's on a new phone but it says there's £0.00 on it (So may have saved wrong 24 PW's)
I have a 2nd nano ledger device I used to set up Bitcoin 3 that the live app does recognize fine and I can send transactions from.
I can see both Bitcoin 2 and Bitcoin 3 accounts on the live app on my phone.
My phone is the only place I can see the Bitcoin 2 funds as when I set up the nano ledger on a new device it reads £0.00 (Again as seems I saved the wrong 24 PW's)
So am reluctant to throw this phone away as is the only place can see the Bitcoin 2 funds
What I wish to do is transfer the funds from my Bitcoin 2 account to my Bitcoin 3 account
I can think of about 4 reasons why your balance might show up as zero.
1. Ledger Live has sometimes sync issues for whatever reason. There are support articles on Ledger's website that give some advice how to handle Ledger Live sync issues.
2. A wrong set of mnemonic recovery words, usually poorly documented without details when wallet was created, for what reason, ...
3. Your coins are on an account with a different address format. I guess Ledger Live should be able to detect this, but I don't use Ledger devices, nor Ledger Live.
It's also possible you created multiple accounts for the same coin with your set of recovery words and after recovery only the default account has been recovered which might not have any coins in it. Different accounts have different derivation paths. I'm not going into much details about this for now.
4. You may have used an optional mnemonic passphrase as extension of your 24 mnemonic recovery words. Any deviation from your initially used optional mnemonic passphrase will result in an empty wallet.
I have some doubts that it could be no. 4 because this is an advanced feature (sort of dangerous if you don't understand how it works and if you forgot to properly document the exact mnemonic passphrase extension).
If you can see transactions on the phone that shows you a non-zero balance for account "Bitcoin 2", can you check what address format the inputs of your own spending transactions use? Let us know if it's legacy, Segwit or Native Segwit (probably unlikely it's Taproot).
If you reset Ledger Nono #1 which initially had keys for the wallet which had account "Bitcoin 2" to restore a wallet with your 24 recovery words which may be a wrong set of recovery words, it could be that you now permanently lost coins of "Bitcoin 2", unless you find the correct set of recovery words OR the recovery words are correct and one of my other reasons prevents you to see the coins.
Gosh, this sentence is too long and too much of a mess, but my brain is sort of frozen this evenening.
