i pad and bt sport
 

I been watching bt sport via their app through my I pad on to my tv, I now get no picture just sound and the following message

sorry you cannot use the bt sport app with mirroring enabled

any ideas how to disable mirroring and get the picture back

on the bt forum several other people have had this problem but no replies have been forthcoming
