The YouTube app on your phone or tablet is designed to cast to Chromecast, but the cast button might be missing or not working if your device, Chromecast, or network are experiencing issues.
Ensure your phone or tablet and Chromecast are connected to the same Wi-Fi network.

YouTube content can encounter HDCP or High-bandwidth Digital Content Protection errors when casting from a phone to a Chromecast, especially if the TV or display device doesn’t fully support the required HDCP version.
