Cannot add music to any Playlist
I cannot add songs from my Apple Music (formerly iTunes) library to any of my playlists.
I have tried to drag and drop, add by means of "edit" or right clicking on song and then selecting "add song to playlist"....nothing works.
All of the afore mentioned above worked before however; since uploading the new Catalina/Apple Music it does not work.
Maybe an update is required? When can this be expected?
