I've been using Macs for over 20 years now and they seem to be HARDER to use. I have iTunes 220.127.116.11 and latest iOS. My iPhone is connected to my iMac, and I manually manage my playlists from iTunes to the iPhone. I dragged-and-dropped, one by one, several play lists from iTunes onto my iPhone in the left sidebar. Moments later I checked and the playlists were not on the phone. So I went to do it again, only the playlists were gone. No, I did not delete them. I have no idea what happened. It used to be you could just drag and drop stuff on your phone and BAM it was there. Now I have no idea what's going on. I wonder if Apple's software engineers do too.
