Before you start casting, please ensure the device you're casting from and the TV with Chromecast you're casting to are on the same Wi-Fi network.
Using the Cineasterna app on iOS/Android
Open the app and tap the Cast button in the top-right corner of the screen 
. Then, select the Chromecast device connected to your TV.
Start playing a film in the app to cast it to your TV.
Once casting has started, you will need to re-enable the subtitles. You can do this by clicking on the subtitle box in the top-right corner of the player.
Using the Cineasterna website in Chrome browser
In your Chrome browser, start the film. Next, select "Cast" from the Chrome browser menu and choose your Chromecast device.
After you tap the cast button , you may need to tap Allow to let the app find and connect to devices on your local network.
If you tap the cast button and your TV or Chromecast does not appear, this indicates that a setting or network issue is preventing Cineasterna from detecting your device on the Wi-Fi network.
