I want the closed captions to be yellow in color with a transparent background like I have it set on my TV and on my Apple TV. When I use the Channels app the text is white on a solid black background and the text is larger than I want. Is there a way to fix this?
A new beta of the tvOS app is available via testflight with custom styling for captions. The styles can be changed in Settings.app under General > Accessibility > Captions.
