First channel you select in the regular guide will play fine. While playing if you bring down the quick guide then try to play another channel it just spins and spins with no image or sound. Sometimes takes 2 or 3 times to happen but it's consistent. Confirmed on 2 different onn 4K Gen2 boxes on my LAN.
Problem does not exist on my Pixel 8 Pro in the same environment.
If you back out of what you are currently watching and choose a different channel in the regular guide it doesn't seem to have a problem. Only when browsing between channels using the Quick Guide.
Submitted diagnostics 3 different times between 2 boxes.
