I've had those "some little wrinkle and the whole thing falls apart" moments. The worst thing is googling them and finding huge threads of complaints from years ago. Apple is a powerhouse at building high quality new software, but they never listen to user feedback and fix the old stuff. Sometimes things even gets worse! e.g. the AirPods Gen 1 let you change the double-tap action between Next Track, Previous Track, Play/Pause and Siri. Obviously people have asked for more customization options like Rewind 5s. Of course, AirPods Pro Gen 2 removed options and now you can only choose between Noise Cancellation and Siri. At this rate the next gen will remove touch controls completely and force me to talk Siri ๐ฑ.
The TV might be the problem if Samsung cheaped out on the CPU, or has too much bloatware running in the background. It's infeasible for app makers to test on every TV model and every OS update. It's easy to see how an update could cause a new type of system lag that hadn't appeared during testing... That said, I remember Apple TV also didn't have good options for selecting quality. It's also pretty plausible that Apple didn't code it to fall back to a lower quality if the CPU couldn't keep up.
I honestly don't know what that silence would be like. I've spent my programming career jumping between domains, becoming an expert then moving on to find a new challenge. Now I'm building AI stuff for medicine.
In my down time I learn languages, watch videos about physics and math, and play puzzle games.
My brain actually won't let me stop. Boredom = pain.
