  1. the hard reboot worked on my 9.7 ipad

  2. I’ve changed my setting to pretty much what you’ve suggested. We’ll see how thing work.

    My real bug-a-boo it when my iPhone is raised for me to do something, more often than not, iTunes comes up saying it is playing or not playing a certain song in the background. I then go in and double tap my HOME button locate the iTunes open screen and swipe it up and closed. The cycle repeats itself MOST frequently. How do I STOP iTunes from doing this.
