it doesn't work anymore. I get only: "Sorry. An unexpected error occurred". App uninstalled, once again installed, login process performed, all looked fine and at the end after the first login - An expected error occurred. Letting your users be Beta-Testers is pretty unprofessional.

The fact that the error still occurs, despite using the latest version, is not as it should be. Please call us at 0800 - 285 85 85 so we can investigate why you are still receiving the error message. Best regards, TK-Ident App

As clunky as one would expect, given the legislation, but functional. Please add a language option separate from the system language, as the English localisation is, as always in Germany, terrible, and I would much rather use a comprehensible German UI.

I received new card with a pin. The pin in the app doesn't work. After 6 unsuccessful attempts app just produces unexpected error screen. That's it. I had to remove all app data from the system (clear cache and data) to get it back to registration. Very complicated process, I believe most people can't handle it.
