I've had no specific iOS 8 issues, but my wife (iphone 5) says that FB now keeps locking up.
Mind you, today I tried to load a single music video to my daughters ipad, using my wife's desktop PC.
-can't have two "profiles" on the same itunes.
-you can have two music libraries, but you cant sync with a music library if it is synced with a different library, gah.
So I pull out the laptop with my daughters original music library and media. And itunes. Of course with iOS 8, itunes refused to play until it was updated.
Two hours later, I had achieved what could have been done in two minutes with drag and drop.
Guess what I'll be replacing the ipads with?
