I got a letter with the code for the app, tried to login, but then had to create an account on pc, where I now theoretically get electronic mail from the TK, which I can't read, because I need a login PIN via SMS, but we have no mobile network here. That's why I have to use the app, which only tells me to get the code via letter, which brings me back to the start of this loop. long story short: I don't get any more letters from tk anymore, only electronic ones, which I can't access. Loving it.

We are sorry you are having problems with login. We want to give you detailed answers. Please feel free to contact our support team at tk.app@tk.de. Perhaps we can narrow down the problem together and help you out. Best, your TK-App

Unfortunately, a poor login experience. Firstly, on the login screen, switching to another app automatically clears the text typed into either the username or password field. I cannot switch to my password manager app to copy-paste my username and password. As a workaround, I used split app view to keep both apps active. Secondly, even after successfully completing the Nect Wallet verification, the TK-App still says verification is in progress. I ended up using an old activation letter instead.
