I’m running a Denon 3500H, 4K Apple TV, Xbox and Sony 900F TV. All my components (Apple TV and xBox) run to the AVR, then one HDMI goes from the AVR to the tv. Historically I could use my Apple TV remote to turn everything on and rarely needed to use my TV or AVR remotes. About 3 months ago one of my components got an update and it stopped working. Any ideas on how to fix this?
