The apple TV remote app on my apple watch was paired and functional before the last Watch OS update to 8.1. Now it is unpaired and I can no longer pair it with Apple TV. It doesn't appear under remote apps and devices on the TV. I have apple TV 4 and the software is up-to-date. They are both connected to the same wifi network. I have restarted both devices. The remote app on my iphone is still connected.
