Apple TV disconnects from display for a few seconds when using the back button
I recently purchase the new Apple TV 4K. I've noticed in most of movie/tv apps (Netflix, Prime Video, HBO Max, Disney+) that when I'm playing the video and press back the Apple TV disconnects from my TV for a few seconds. It will show sometimes that there's no input. I am not sure if this is a problem on my HDMI or the Apple TV device. I used this HDMI before with another Apple TV (prior version with the older trackpad remote but 4K as well). Anybody has any idea? As much as possible, I don't want to change the HDMI as it's behind my wall :-/
