I looked at Charlie's iPad last night and realized that the icons for his music albums were all jumbled up. And, at least one-third were missing!
He had pointed to one of Jimi Hendrix and said 'I want.' It's not really clear what he means by that but, this time, by inspecting the iPad I was able to discover the disarray.
Since my Mac is mission control for Charlie's iPad, I restored all the missing icons and found that he had changed some of the controls.
Another instance of the iPad allowing Charlie a way to try things out on his own -- after which order can be restored.
