Have you downloaded the YouTube app for your Apple TV? I was having a similar AirPlay issue with YouTube from my iPad Mini but after I downloaded the YouTube app and approved my account on TVoS it started working with no hassles. Not sure why they're related but it solved my issue!It look's like everything is working - airplay in menu bar is blue and sometime gray screen with airplay appears for 0,01s but it plays still on mac not on tv.. when I have ATV3 it worked but everytime when I turned on Apple tv and connected connected airplay from safari youtube I needed to make a move in playback bar (go forward) but then it worked normally.
edit: even after trying to airplay youtube when I go to facebook and play video it airplays automatically! but on youtube it only flashes airplay logo

Haha I might have to eat some humble pie on this one - it looks like an issue with Youtube itself, as I can airplay from Vimeo just fine. Apologies to Apple.

It's now working fine for me even with ad-blocking in place.
