Cannot control AirPods volume on Apple TV using iPhone
I connected my AirPods to my new Apple TV 4K. I then opened the Apple TV remote app from the Control Center on my iPhone. When I did this the first time, the mute button in the remote app was enabled and the volume buttons of iPhone controlled the volume of AirPods. After a few hours, when I repeated the above steps, the mute button is grayed out (disabled) and the volume buttons adjust only the volume of iPhone even during playback on Apple TV. Can someone please let me know what went wrong the second time?
Apple TV 4K, tvOS 16
