Android users will now find it easier to access Apple TV content on their televisions with the introduction of Google Cast support. This update currently applies only to the Android version of the Apple TV app, as Google Cast remains unavailable on the iOS version. Additionally, the Android version does not support AirPlay functionality.
To utilize Google Cast, users should ensure that the Apple TV app is updated to version 2.2. In this version, the cast button can be found in the upper right corner of the screen during the playback of shows and movies, as well as in the pause overlay for content that is currently playing. It is important for users to check for updates to access these features.
As this development expands the usability of Apple TV content for Android users, it raises questions about future compatibility and support across different platforms.
