7- Select your Chromecast: After tapping the Cast button, a list of available casting devices will appear. Select your Chromecast from the list.

8- Enjoy on the big screen: Your selected Netflix content should now start playing on your TV through Chromecast. You can use your casting device to control playback, pause, resume, adjust volume, or browse for other content while it plays on the TV.
