@TeamYouTube just got YT premium and I'm super disappointed. The shuffle button doesn't even work for the downloaded videos and the audio stutters when you close the app or turn off your screen. For $16, I would like to have something that actually works.
Thanks for checking. Could you check if your device has any pending OS updates available? If yes, update to the latest version to see if that resolves the issue. Let us know if this helps.
