These are the steps you need to follow to stream Rakuten TV content on your Chromecast using an iOS device:
Your Chromecast and your iOS device must be connected to the same WiFi network. Once this is done, the "Chromecast" button will appear just as you can see it in the picture below.
When you click on the Chromecast button, you will see a list of the available Chromecast; just choose yours.
Your iOS device's Rakuten TV app and your Chromecast will connect and the Chromecast symbol will turn green.
Now when you search for a movie you will see the button "Cast Now" when you get on the movie detail page, please keep in mind that we are still increasing our content available for Chromecast.
If you have followed these steps and the "Chromecast" button isn't available yet, follow the additional instructions here
