I have the same issue, all icons settings available! My phone even says that the pictures are showing on Apple TV, but I get nothing!? Mirroring is on Apple TV is on!? Nothing just stays on yhe Apple TV menu!?
Ok, I uploaded appleTV to the latest release, it showed 1 picture, then i showed the spinning icon, like it is tryying to load something, now it is showing me this screen!! Took like 2 minutes to load!?
