I've noticed my Apple TV 3 recently freezing on YouTube videos (not sure if I paused the video), after 1 or 2 minutes it seems to reboot without my doing anything. Running 7.6 (8130). Runs Netflix reliably, as usual.
Also an old problem has come back, maybe related to 7.6. I wanted to rewatch the first few minutes ot the Apple September event (iPhone 12) using the Apple TV 3, but when I tried I got a message on my iPhone and iPad saying "Apple ID Sign In requested to a device" (obviously my Apple TV 3) near or at my location, and it wanted me to Allow, and type a code number into the device. But there is no way to type the code into the device (Apple TV 3). Strange, because the Apple TV 3 is correctly noted as being associated with my Apple ID. This might be a problem related to 2FA (two factor authentication), some people in 2017 got rid of the problem by removing 2FA from their Apple ID account, i tried to disable 2FA but it won't allow this.
Hoping that I will be able to watch the Nov 10 Apple Event using the Apple TV 3. If not I will use iPad or computer.
