The first thing you see is "relax nothing to approve" only to get the message that there is sth to approve one second later. Maybe you can fix it. Other than that okay

I had to wait for a letter to receive Best Sign password, this is why I decided to go to the Post bank office.

Garbage, will rarely work on older phones. The app opens and closes by itself and the confirmation windows is gone. I have a samsung A14. You need a new phone with high ram for it to work reliably. Fix your application it shouldn't be this heavy and unreliable. I'm a developer myself. I know what im talking about.

Can't change app language, app adopts phone's primary language!! So let's say phone language is English, u cant set app language to German!!

Forces phone restart! I know my ID but not my password so when I go into the screen to get my password, I enter two letters of my ID and then the app forces my phone to shut down and restart.

It keeps saying that the password is incorrect, but it's correct! Extremely annoying 😡
