🐛 Bug Report

This only happens on one phone, which happens to be a Samsung Galaxy S9 that previously had no problem. It started happening today and seems to be related to that specific phone. Old app versions that worked before no longer work. It appears that the app no longer has permission to access the lock file. Tried giving it permission to write external storage but that had no effect.

Teammates have also run into this on a Pixel 4 and a Pixel 3 XL, so it is not specific to the Galaxy S9. We have not been able to isolate steps to reproduce the problem. There is some evidence that it is tied to Android's backup system -- one teammate got past this by setting allowBackup to false.
