Why can I no longer drag-and-drop files from a CD into iTunes on my Mac?
I have always dragged files from CDs into playlists that I have set up in iTunes on my iMac. Recently it just stopped working. When I start dragging, instead of seeing a little green square with a plus sign, I see the "not allowed" symbol (circle with a slash). I typically copy only selected tracks from a disc into a playlist that I have created and named in my iTunes Library, so the "Import CD" feature is useless.
I would be grateful for any help. My iTunes version is 12.9.4.94 (!) and I am running OS Mojave 10.14.4.
