For that past 8 months, iTunes has been crapping out. I have 10 playlists, and none are able to add any additional music selections, whether new and online, or purchased and downloaded. None can be added. I first updated all software and then all components of the windows 11 PC, to no avail! I updated all drivers. I finally uninstalled and reinstalled Apple Music, to only find it still doesn't work. I am finding that even existing songs in the playlist, whether purchased, downloaded or not, are no longer able to play or be found?!?! Even though I can look through my library and play the songs individually, I CANNOT ADD THEM TO PLAYLISTS! This is totally unacceptable. Anyone have similar issues with Spotify, or Pandora? I have not experienced these issues with those platforms.
