Playlist not rotating

Having a problem getting my playlist to rotate.

  • When I open the playlist through my browser it works great
  • When I copy the playlist URL to another tab it works.
  • When I open the URL in a private window and login it does not rotate and is missing this - Screenshot 2020-02-18 at 13.28.27
  • When I open a private window login and then navigate and select the playlist it works fine

I upgraded my instance version today, to make sure that was causing an issue!

Anyone got any ideas?
