My girlfriend just bought the subscription to Apple Music and when she uses the Mac iTunes to add songs to her playlists, the songs aren't appearing on her iPhone unless she first adds something on her iPhone to her music. If she adds something from her iPhone, the songs instantaneously appear on her Mac. We tried turning the Playlist sync feature on and off again, but that didn't work. She also logged off from iCloud on her phone, but that didn't help either. Anyone have a suggestion on how to get it to work.
