@gtrautmann Welcome to the forum!

Did you try to deactivate “smart punctuation” on the iOS app / keyboard?

Can you login to the web vault (vault.bitwarden.eu in your case)?

… if you also can’t login to the web vault, then you should check if you really use the right email address (and/or typo?) and if your really use the right master password (and/or typo?)…

Check also with your emergency sheet, if you use the correct credentials.

And can you remember, ever (or recently) changing your email address or master password?
