Hello dear Migros

My app has not been working for a few weeks now.
At the beginning I could no longer activate vouchers. I then deleted the app and reinstalled it. However, I can no longer log in. I have also reset the password, unfortunately without success. I get the error message in the app: "A problem has occurred".
I now only use the app for my purchases - I haven't had the card for a long time. I find it very frustrating, I can't benefit from the Cumulus offers at the moment.

Information about my cell phone:
iPhone 5s
OS version 11.3.1

I hope the problem can be solved.
Thank you for your help and best regards
