Why is my Apple TV not appearing as an option on AirPlay?

If an Apple TV is not appearing as an option on AirPlay, it could be due to several reasons. The devices may not be connected to the same Wi-Fi network, or there might be network connectivity issues. It's important to ensure both the Apple TV and the source device are using the latest software updates, as outdated software can cause compatibility problems. Additionally, check if AirPlay is enabled on the Apple TV under the settings menu. Interference from other wireless devices or networks can also cause connectivity problems, so one should consider reducing potential interference or moving closer to the Wi-Fi router. Furthermore, firewall settings on a router can prevent devices from communicating with each other, so reviewing those settings may resolve the issue. If these suggestions do not address the problem, restarting both the Apple TV and the source device can often resolve temporary glitches that might be preventing AirPlay from connecting.
