My music playlists are not syncing to my iphone using itunes??
I had faced this issue 10-15 times and it was random sync or not. Finally i got below article and i tried it...it worked well as of 12/2021.

- On your device, tap on the Settings app to open it.
- Scroll down until you reach the "Music" icon and tap it. Select "Music" from your Settings menu. ...
- Next to "Sync Library," ensure the option is toggled off.
Then go and select the playlists in ITUNES. Finish the sync....
Then I turned on SYNC LIBY again...and all 30-40 playlists showed up on iphone. Hope this works for you...and saves you a lot of pain! Live for the music!!!
