Ring App for Apple iOS keeps forgetting my login after EVERY App Update

The Ring App for Apple iOS as such works fine, and I can login with my Ring account, BUT … every time there is an automated Ring App update, the app forgets the login credentials, and I have to login to the App as if it is my first time.
Besides some inconvenience there is a BIGGER ISSUE: when this Ring App has no valid login, the App will NOT NOTIFY me when the Ring Doorbell is pressed/called, so then I miss the change to answer and connect with the video/audio interface and talk to my guest !!
So this is a bug-fix request (not sure if this community is the right place).
