@youtubemusic Please fix the iOS bugs - 1. It stops playing/becomes buggy when music controls on lockscreen/headphones/apple watch are used. There are so many UX bugs here and there which are frustrating. The player shows that the music is playing but there's no output.
We haven't seen any similar reports yet. Could you try uninstalling and reinstalling the app to check if that makes any difference? Note: this might delete your offline data. Let us know how that goes.
