I also watched early this morning, seemed to work fine at 2-3am lol.
I did notice something strange while watching Capt Marvel only. There seemed to be an HDVision/HDR10 encoding issue which made scenes switch white balance quite jarringly. Streaming off Fire TV 4k stick, and I know my cables/equipment is capable. Later on, I have to restart my Fire stick to view an episode of the newer content (Mandalorian, Avengers, Marvel), but works fine with older content (Avatar). Since the system went down, I have not had the opportunity to troubleshoot.
