Voted 5 stars and here I come to fix it. I'm trying to open the app but both the biometric and password lead to unlimited waiting time for the app to run. If the screen dies you have to repeat logging in. I have been trying to log in for 10 mins already and I give up.

Worse than having a file folder The login, security check and ... are so archaic that I am forced to keep a file. Just to add a new vaccine, I had to waste 10 mins and I am pretty sure it's not the right one. To be fair, I think it's not the developers, but the German Law Makers to blame... when you have to abide by 19th century law to a 21 century app, you can't make it useful.

Set up and Log in took months. + No clear overview over status of requests or responses received. The app is messy and confusing, not at all intuitive. Very disappointing.
