I’m having the same issue. I have checked both devices for updates, I have ensured they’re on the same network, I have rebooted both items and my WiFi router. I have even contacted Apple, however we were disconnected and I never got a call back. My air play works just fine, I can pair my phone with the Apple TV, the original remote is fine, but it will not connect my Apple Remote from the control center on my phone to my Apple TV. It continually says searching like it can’t find it. I am open to any suggestions or if it’s an update issue to know that I’m not alone lol thanks for your time!
