I see that option on my phone and tried it, but playlists don't update. Don't see this option in the browser app.
Edit: and yea, iTunes sync is on, cuz when I add music to iTunes it's automatically added to Google music and all playlists are updated.... I'm trying to get playlists to update even when I don't add music
what you mean by this... Why not make a playlist?? how would a playlist update if you dont add music to the playlist??
all your songs are sync when you add music to itunes. If you dont add songs then your music cant be updated obviously
