Maybe someone has whatsapp installed and can test it?
Why do you want to test it with WhatsApp if the user claims it sends fine? It just sounds like a coincidence.
Mycelium is an HD wallet so it can generate different addresses for the same HD account, the aim being to use each address only once for privacy reasons. It may be hard to tell which addresses belong to which account.
If there are several accounts/wallets, they can be shown together or separately. If the setting in the app is to show them separately (it's an advanced feature), and the selected account is not the one where the address was generated, the app will not show any incoming bitcoins on the Balance or Transactions tabs. However, regardless of this setting, all accounts and their balances are listed on the Accounts tab.
Has your transaction been confirmed?
There may be various explanations why your party doesn't see your bitcoins, the least likely of which is a malfunction in the Mycelium wallet. More information is needed to investigate this; at least, the address you sent the money to, to begin with. If you don't feel comfortable sharing it here, perhaps consider writing to Mycelium support.
dooglus tested it with an email app. The one that had the problems used whatsapp to share the address. So i wonder if the problem might be in that combination. I mean the one that has the problems claims its a repeatable thing.
I dont think it makes much sense to share an address when mycelium then actually shares a different address. And the address doesnt belong to the wallet. No coins came in there.
I didnt hear about different accounts, ill ask him, though when you say all balances should show up then its probably not the problem since nothing showed up.
The transaction was confirmed, yes.
The address is
https://blockchain.info/address/1AzDd8rEGZfE22bXhPhpeF9Bi9uQFEUvsT though i see now outgoing transactions. I need to ask him if he took it out but i doubt it since he would have informed me. I will ask him anyway. The 2 transactions were to test if the address works, the third was mine. The next two are unknown to me as of yet. Maybe everything was cleared and he really didnt tell me? Ill ask him.
