Received Apple TV for X-Mas. I have an iPad (4th gen) and connected it without a problem. I mirror the iPad and see the home screen and icons fine. Everything works except WD Photos, which blacks out the entire screen when I run it. Collapsing the app by hitting the home button twice displays the shrunken app correctly, but when tappped to enlarge, the entire screen blacks out on the TV. The iPad screen displays the app correctly. Oddly enough, a friend has an older iPad (gen 2) and WD Photos works fine. What am I doing wrong?
