Exactly the same issue here. Running latest server version on a Mac.

This appears to be the problem:

In case this helps anyone - this is how I got this working (the method was taken from another post on here so I take no credit, but I can’t find the original now):

• Click on the three dots on the right of the music library (not playlists), then manage library -> edit.
• Don’t make any changes, and save. A scan of the music library will run.
• Import playlists as normal. Note that you’ll need to export your music library to an XML file manually if using the Music app - and Plex looks in the ‘old’ iTunes’ location - so /Users/username/Music/iTunes/iTunes Library.xml on a Mac, not sure on Windows.
  That got it working for me. I’ve tested a few imports and all looks good. You’ll need to come out of playlists and go back in to see any changes. If it stops working I would hope the refresh of the Music Library would get it working again.
  Hope that helps someone.
