And because of the “seed” issue, of course I have the password to get into the wallet and then the “possibility” to display the seed, but this consists (for whatever reason) of a passphrase with 30+ numbers, letters and special characters. And when I try to sign something, the app always crashes completely and has to be restarted. So under “Sign message”. And what is also extremely strange is that when I go to the info where the characters for HD, Lighnting, Seed etc. are displayed, i.e. above where you normally see the seed, the “Encrypted” symbol is missing, but it is displayed everywhere when I try to create a new wallet.
How can that be? That it can't find the key, which is apparently stored somewhere on the phone, and that's why the wallet no longer works? So it's really more than just strange....😑😒 After all, the original €260 in Bitcoin I bought has now turned into almost €350, which is at least something positive.
In any case, I don't know what to do anymore
Anyways, have you already tried to restore your seed phrase and your passphrase by ticking "Extend seed with custom words" below the seed?
Because if the seed phrase and passphrase are correct, you can create a copy of that wallet without the issue of you existing wallet.
BTW, please use english when posting to this board, it's part of Bitcointalk's rules:
