"This iPhone is Open in Another Window" error
I have song files on my MAC that I want to sync to iTunes/Music. This has ALWAYS worked. Please do not suggest "Just use the cloud" because many of my songs are different versions, not available on streaming services, higher quality, etc. BUT, when I go to sync recently, it will not allow me to click. my iPhone in left hand panel as I always had to sync playlists. INSTEAD, it just says "This iPhone is Open in Another Window". But it isn't? I've closed everything else. Re-started my Mac, etc. Same error over and over. Can I get rid of "This iPhone is open in another window" forever and ever? Thanks!!
