Hey @BenHenning
From my investigation, this seems to have been caused by automatic backups. We allow this feature in our manifest.
From the look of things, automatic data restore is a problem when an admin is trying to reset a forgotten admin password.

Is it important for the app to be able to backup to the cloud at the moment?

We can disable backups by setting android:allowBackup to false in the manifest.

Would you rather go with a different solution for this issue?

Hey @BenHenning , @adhiamboperes ,
To Resolve This Issue, I Believe Disabling android:allowBackup By Setting It To false Would Be A Good Solution. Can I Proceed With This Approach?

This problem seems most likely to affect testers and developers more than real users, and we haven't yet had any user feedback on problems like this (i.e. data unexpectedly being restored after reinstalling the app).

With that in mind, I think we should close this issue until we hear real feedback from users.
