Hi! I'm having a similar issue. I'm on a Samsung S21. Carrier should be irrelevant because it happens on data and wifi. I have not tried using a computer yet. I can delete one song from a playlist just fine (by sliding it on the playlist view and hitting delete), but if I try to do any more, it deletes from the playlist view but not the player view. This causes the two to desync, so the song playing according to the playlist view is a song or two (depending on how many I tried deleting) after the one that's actually playing if it's further down the playlist from the song I tried deleting. It also affects selecting songs to play from the playlist view. This happens when I'm deleting while listening to the playlist I'm editing and when listening to a different playlist. This has happened on all playlists I've tried deleting multiple songs from for a while (I can't say exactly how long). There is no error message. I might remember a song showing back up on the playlist view after a while, but I cannot remember it clearly enough to say it happens. One image is after I tried deleting one song, and the other is after I tried deleting a second song. Any songs above the glitched ones in the playlist are unaffected. This is very annoying and I'd love to see it fixed soon!
