I have an annual subscription for the iOS App Calibre Companion from the German App-Store (iPhone 7, iOS 13.5.1).
Immediately after the update to Calibre Companion Version 2.0.11 (2), my Apple-ID password has been requested. Then comes the message that I have already subscribed to the App and then the message "Restore Sucess". Only a few seconds later, my Apple-ID password is requested again. And so on, no way out.
I have deleted the App and made a new installation, but the Problem appears again.
The app is not usable for me after the update. Anybody with the same Problem ? Maybe a bug in the new version ?
