Corrine has an iPad Mini that she uses with Airplay and Apple TV. She upgraded to iOS 8, but she can't see it. Apparently there is a mirroring issue with the Mini after a recent update. Leo says it's important to also update her Apple TV when she updates her iPhone. If she does that, chances are, it'll work.
The chatroom also says she has to scroll deeper into the menu to see it. Leo says she can go into her contacts application in the Mac, merge all of her contact duplicates and it'll merge them on the next sync.
