Unable to authorize computer for Apple TV purchases and login to Apple Music
I have been trying to authorize my computer to purchase movies on AppleTV (I have used this computer before for AppleTV) & it keeps saying there is an error. I deauthorized all other devices (I no longer use them) & even tried deauthorizing this one to reauthorize but no luck. I also can't seem to login to Apple Music. I used the same login to post here no problem. Any ideas?
