l tried tonight to show some photos from my iPad on a friend's TV, via Apple TV and AirPlay. I could mirror everything up through the album thumbnails, but when I selected any individual photo the TV went black. When I got back home, I tried it on my own ATV; occasionally photo would appear onscreen, but swiping through the album did not change the TV display. More often, it just went black as before. In fact, AirPlay was extremely sluggish and reluctant to connect. Other apps, such as YouTube, play perfectly on the TV. I seem to recall this working before. Is this a new bug in 9.2.1?
