Playback on Google Chromecast is now available with the Prime Video apps for iOS and Android.
To use Google Chromecast, you need the most recent version of the Prime Video app for either iOS or Android.
From the Prime Video app, select the Cast icon, then select the Chromecast device you wish to use. Once you have selected a title to watch, it is sent to the TV that your Chromecast is plugged into.
While using Google Chromecast, playback, subtitles, and audio settings (such as language tracks) are controlled via the Prime Video app.
Note: To start playback, your iOS or Android device must be connected to the same Wi-Fi network as your Chromecast.
