I was backing up my phone to prepare it for the battery replacement and while I was at it, I moved the order of songs in each of my playlists. I then synced my phone. After I ejected it and went to look at my playlists, the order of the songs wasn't changed even though on my Mac mini it shows they are. I tried on my iPad and it worked. I tried syncing three different times then I turned off my phone and rebooted, but that didn't work either. Is it something to do with iOS 10.2 update I did yesterday or what could be the problem? Thanks for any tips!
