Then a popup says cannot play video. Before this when I’m navigating to the video everything looks fine. Do I need to do updates to the Apple TV? How do I do this? I hardly use it because it’s in my guest room. My phone is updated.
If it used to work and stopped, power everything down, phone, ATV, your network. Reboot network upstream to down, then everything else. Try again. Sometimes we give these things too much credit for figuring out the massive amount of requests we make of them but they do get confused.
