In the last few days my Apple TV 4K has developed this issue. After roughly 20 mins of play the screen freezes but the audio continues. Apple of course said to do the regular things(reset, sign out etc) and then told me that it was my HDMI cable. It's been the same cable for the last 2 years. Nothing has changed about my set up. Nothing. Strangely it's only with Disney titles. Anyone else having this issue?
