I have music synced to my iPhone in Plex, and with the latest release I have noticed that when I play music now that the tracks skip like I'm listening on an old school CD player...sometimes it skips forward, sometimes it skips backwards and plays a bit of the song it just played...
I have also noticed that it's not a track issue, because sometimes a track will play through flawlessly, and then the next time the same track will skip several times...
I feel like it's a Plex app memory issue, but have no idea...
