Using a Pixel 3 and upgraded Android 10 yesterday. I use Phonograph as my music player and CoverGrabber to get album artwork where it doesn't show up automatically. Since the upgrade to Android 10 less than half of my music album thumbnails show up in Phonograph. When I use CoverGrabber, I can select album artwork, it will fill the header space as happens in CoverGrabber, but when I go back to list view in CoverGrabber, the artwork is not there, nor is it in Phonograph. I have restarted my phone, I have tried uploading the artwork so it's on my phone, but still no joy. I have also tried with a different music player and the same thing happened.
Any help would be very much appreciated.
