I have downloaded music on my phone and it used to play it on offline mode just fine. But once I logged into my YT account the app started to act oddly. If I open the app without internet it just doesn't give me access to my playlists. And today when I opened it with internet the music from my device just doesn't play at all. Songs just get skipped without any music. If I manage to stop this and make it play, the sound doesn't come out. What is this?
