"Already Authorized" fixes aren't working
Before upgrading from 10.8 to El Capitan, I had started an audiobook on my iPhone. The book had been purchased by my wife using her ID. I had authorized from my computer then sync'd. After the upgrade to El Capitan, 16 items in my iTunes Library cannot be sync'd and the audio book is one of them.
I tried everything here: If iTunes prompts you to authorize your computer when you try to play iTunes Store purchases - Apple Support
I deauthorized my computer as well to no avail.
When I go to play the book on my computer, it wants me to log into my wife's apple ID. It isn't supposed to work that way. When I use my own appleid, it says it's already authorized. TIA
Sigh. ðŸ˜
