Hi,
Poweramp Version is latest 2.x from playstore (during test period still). I also registered for the beta programm, to check version3.
Android Version is 8.1, self compiled rom, based off aosp. Meanwhile i have changed SQLiteCursor.onMove function, to not throw an exception, but only return false (although, this has been aosp code i changed there...). This should workaround the issue i guess.
edit: just compared the rom against aosp more detailed...seems to be a rom issue. sorry for the trouble
