Well, the results are in: On my old Galaxy s7 (Android 8), running Bubbleupnp 3.6.8.2 (arm64-v8a), I was able to delete the Media Storage data, and reboot the phone, as you suggested. And, Bubbleupnp can now pass album artwork (music mp3's with embedded artwork on an sd card) to my Pioneer SC-68 receiver - as it has always been able to do in the past. That's good. However, on my new Galaxy s20 (Android 12), I cannot delete the Media Storage data, as the app no longer allows a user to do this. What I was able to do was remove the sd card, reinstall the latest version of Bubbleupnp, and then, reformat the sd card using my PC, and put a fresh copy of my music files on it. I then reinserted the sd card, and turned on the phone - expecting this action would force an Android media rescan of the sd card. The s20 is also running the same version of Bubbleupnp as the s7. The result: No artwork being passed to my receiver. :-( The only conclusion I can come to, at this point, is that there is something in Android 12 that is preventing the artwork from being passed, or all of my efforts with the sd card, did not actually force a media rescan of the sd card - and I'm stuck with a media database in my s20 that is somehow degraded or corrupted. Hopefully I'll be able to come up with some more ideas to try out - but right now, I have none. Again, thanks for your suggestions. I'll continue to work on this.
