Closed Captioning is available for each of the films offered in the WBFYC app. Once you begin playing one of the films, the closed captioning feature will be available in the playback settings, located at the bottom of the screen. From this menu you will have the option of toggling captions on or off. Additionally, you may go into the closed captioning settings to alter the appearance (color, font, positioning) of the captions.
On the Desktop and iOS applications, you will see an icon in the bottom right corner that looks like a "Message Bubble" which you can use to access the Audio & Subtitles menu.
For Android, you will see a "CC Button" in the bottom right corner instead of the "Message Bubble" used on Desktop and iOS. Below is a screenshot for your reference:
While the movie is playing swipe from top to bottom on the Siri Remote's Touch Surface. A menu will appear, use the Touch Surface to select and enable subtitles.
