We have a user who is unable to get his Android app connected to his xMatters account. Every time he clicks the link to scan the QR code, the app crashes with message "xMatters has stopped". He is able to log in manually, but doing so does not add the Android device to his account so he is unable to configure alert notifications to be sent to the app. He has tried uninstalling and reinstalling the app, and he has checked all of the app permissions. Is there some other way to set up his Android device?
