Help!! I have a problem with airplay from ipad 3 to atv3. Up to tonight never had an issue in 6 monts, but now music, or video stops if i switch apps or if ipad sleeps. Even playing from itunes,or content from safari. Not got a clue where to begin. Damn sure I've not changed anything! Any help much appreciated. Ipad is on ios6.0.1 (10A523) and atv3 version 5.1.1(5433) Cheers.
