Youtube, Spotify, media content forces disconnect when using exhibit with video content

[GrafZahl02]

Hey,

thanks for this wonderful app. Sadly we have a big problem. We show a videofile on 80 AppleTVs with Exhibit and Airplay is working normally. But if one will share content from YouTube, Spotify or other media content, Airplay disconnects immediately. This happens very often.
After disabling Single App and enabling conference mode, everything works fine. Changing back to Exhibit with a videofile, sharing media content through Airplay lead to disconnects again.
Can you confirm this problem and please solve it at best.

Here you can find our video. Our students love this background, if the AppleTVs aren't in use.
