I have Netflix (basic, no 4K), Peacock, HBO, Paramount +, Disney +, Hulu and Apple TV (each as an individual subscription), all of which I watch regularly and for prolonged periods of time. Except for Apple TV content, never a bad moment. For example I was watching CODA, everything was fine, no hesitation or pixilation, suddenly a gray screen with no specific cause listed. I get past the gray screen (push OK) then hit resume and I'm good for another half hour to 45 minutes. I could try re-installing the App, this just bothers me because it only happens with Apple. My connection is wireless but I have two other TVs farther away with walls in between that work fine without any signal problems and my primary TV (a HiSense 4K ULED with Android TV, the one I use most) is no more than 15-20 feet away from my router with an unimpeded line of sight. I live alone so I'm not using a computer while watching TV while conversing with Google Home and streaming music in some other room/s or on my phone. I guess I might try uninstalling and reinstalling the App on the HiSense, it just occurred to me that I don't think I've ever watched Apple TV on either of my other two TVs so I can't say if they have the same issue. Thanks for your help and interest!
