apple tv and IOS TV remote app
I was exploring the TV remote app on my iPhone 8+ (IOS 15.5) and noticed it switched my apple TV on, allowing me to control my downstairs Apple TV (4th gen) and upstairs apple TV (3rd gen), although it's only very limited control.
A day later, I discovered my apple TV remote devices no longer work. How do I reset my apple TV remotes so they control their apple TVs? How can I undo whatever I did.
Apple TV HD, tvOS 14
