Airplay works on my iPhone to Apple TV but not on my iPad?
I purchased Apple TV back in December and cannot get it to work with any iPad in the house. We have three iPhone 5s, and Airplay and Airplay mirroring works on two of our iPhone 5s to our Apple TV (can't get the third one to work). However I cannot get either of our iPads to work. Both have the Airplay icon and when you hit connect to play a video I get "An unknown error occurred -6722". When I hit connect and Mirror, the blue bar comes across the top screen but never plays through Apple TV and about a minute later it disconnects after never appearing on our tv. All of our devices have the current version of iOS 7 (iPhone, iPad, and Apple TV are up to date). I've tried restarting and rebooting with no luck. I don't think it's our wireless network because why would Apple TV work on two of the iPhones then? Please help!
