I have iTunes 18.104.22.168 on my PC and iMac. I used to be able to copy songs from one library to the other via the iTunes sharing option. They are both on the same account with Apple, but now I cannot copy. When I drag and drop, nothing happens. I can't find another way to do it other than using an external source to copy, but I'd like to do it within iTunes! Any help? Has this option been turned off in the latest release? The only thing I can think of besides upgrading iTunes to the latest release is that I was at 5 computers authorized, so I deauthorized all of them, and re-authorized the two computers that I'm using in this scenario. Thanks in advance. I'm normally pretty adept at finding things on my own, but I can't find anything on that helps me here.
