Assume we have an album with following properties: Artist tags are different Album Artist tags are (mistakenly) different Album tag is the same "Join albums" setting is enabled Poweramp v3 would show this as separate albums according to their Album Artist tag. Now we copy the album to PC, clear Album Artist tags (everything else left as is) and upload it back to the phone. Poweramp detects file changes (as shown by circle-ish animation on top of the album list), but is unable to "recombine" the album back without full rescan, which feels to be an overkill in the situation... is this a bug or not?
I had the same problem with beta 795, Xperia XZ2 Premium and Sony WH-1000XM2. Switching from hi-res output to OpenSL ES solved the problem, but switching back to hi-res did not break it again (and I'm pretty sure it switched back properly, cause there's noticeable difference in volume between the two). Now I can't break it back even if I restart Poweramp or reboot the phone itself. Weird, but hopefully helps someone.
