Test the programme and the player together
Select a programme you know carries captions. Open the app's subtitle or accessibility menu and look for a track that matches your language and need. Closed captions can include sound cues and speaker information. A translation subtitle may focus on dialogue.
Try one live and one on-demand item
A service can offer different caption formats across live and recorded programmes. Test one of each. If the track appears in the menu but the text does not render, check the app version, subtitle format if available and whether the same item works on another supported device.
Check the settings with the person who uses them
Read the text from the usual seat and confirm its size, background and placement. Restart the app and see whether the selected track is remembered. For a support report, include title, time, language, platform and whether a track appeared in the menu.

Questions readers ask
What is the difference between subtitles and closed captions?
Subtitles often represent spoken dialogue or its translation. Captions can also describe sounds or identify speakers. Verify the exact track in the programme menu.
Why is the caption setting present but no text appears?
Choose an item known to have captions, check the language and compare the same title on another supported device. Report whether the track was listed and whether it displayed.
