Q: Airplay Mirroring - Issues with device list

Hello,

I'm at a small-med school district. We have about 100 Apple TVs, most on projectors so that teachers can display information from their IPads onto the board for the class to see. As of recent (and with no particular cause or reason from what we're aware) when a user brings up control center and attempts to Airplay, the list of available devices populates, but then devices rapidly appear and disappear from the list. Particularly this causes an issue when navigating the long list of devices, as it can prove near impossible to isolate the specific device the users are trying to mirror to before one of the other devices in it's near vicinity cycles in/out and causes the list to scroll up or down. Doing a hard reset of the specific IPad does fix this temporarily but I'm looking for a better long term/permanent solution.

The Apple TV's are set to sleep after an hour or so, but I don't see this negatively impacting our issue, only having a positive impact. Please let me know if anyone has an idea of how to fix this or maybe what the cause is.

Thank you

*This issue is occurring on both Gen 2/3 IPads some of each are running later releases or iOS 7 or any of the individual 8.x releases (including having tested this on an 8.3 IPad.)
