I thought AirPlay *Mirroring* simply displayed whatever is on the iPad's/iPhone's screen?
For clarity, this isn't the same as choosing the AirPlay button in the video-window. This is hitting the home button twice, swiping all the way to the left, then choosing the AirPlay button from there and sliding the Mirroring switch to 'on'.
What happens under these circumstances with the Sky Go app? Is there just a blank area on the TV screen where the content should be?
