If I go to specific albums and try to play them, some will play but most will not. The album art and songs all show up, but after trying to play them, it will only pause for a moment, move the next one and do the same through the rest of the album.
I can play all songs on shuffle and it will play a limited selection of songs, but going to the albums that some of those are on will only allow those particular ones to play and the rest of the album fails to load.
I have my entire music collection uploaded via Music Manager and am able to play all of it with the same account from my phone also running 7.0 and on the same network.
I've tried doing a factory reset, but that didn't resolve the issue. Interestingly, after the reset, some songs that wouldn't play before will now play while some that had played before are unavailable along with most of the rest as before.
Is there a way to rebuild the index of my music collection? Why does the Android TV app behave differently?
I hade the same problem on my Mi Box. None of my uploaded music would play. Radio Stations and Podcasts worked fine. Unfortunately the only fix I could find was to grab an older APK from apkmirror and sideload it, and then turn off automatic updates. It happened right after the GPM redesign.
