Android Pro app resets completely

[goetz]

On a similar configuration (Pixel with Android 8.1), I also had that effect recently. Like you described, since the recent update on FW 13443, all the content was kept intact. Now from time to time the HP Prime Pro App will clear Apps and other data, and I am not able to reproduce this. It also does not seem to be connected to corruption of the data after update, as I have cleared the app's data via the system settings (not only cache) and the problem still occurs.

As a workaround: When I had the issue with my apps disappearing I noticed that the backup on the HP Prime in the "Mem" menu was still there. I could restore everything with a few key presses. Performing a local backup on the HP Prime Pro app may work as a workaround against such cases.
