I have a 4th gen AppleTV (the newest one) with the latest tvOS, I have no issue using AirPlay from iTunes on my MBP but am having issues with iOS from my iPad and iPhone. I can Airplay Mirror, but I cannot Airplay audio only (tends to dislike larger file size audio). When I select the AppleTV on the iPhone/iPad, it will connect and show a check mark, then the AppleTV screen will go black (sometimes showing a loading icon), then the connection drops the AppleTV screen returns to normal, and the iOS device unselects the AppleTV. Anyone else experience this issue? Thanks!
