Can not see picture on TV when using Apple TV
Tried to use air play to see iPad content on TV, but only heard sound, no picture. Moreover, when I open air play, I did not see "mirroring" choice.
Not all apps are enabled for AirPlay, that is up to the developer to do. You can't enable mirroring from within an app, you need to swipe up to control centre.
