Amazon Music app has stopped playing on my Roku Ultra. It is not the network, not the internet, not the wireless, not my amazon account, yadda yadda. When I select/play a song, it rescans the entire album and then stops. It doesn't matter which album.
I suspect Amazon is responsible for this, because they are messing with the uploaded music option, of which, btw, I have none. BTW, the app works on all my mobile players for which I only play downloaded music, so I would not know if this is only affected by non-downloaded music.
