Confirm a supplied caption track
Roku's Canadian guidance qualifies captions by service-provided content and notes that some apps manage their own settings. Use a known permitted captioned reference.
An available system control cannot generate a missing authored track or force every app to adopt system styling.
Inspect the offered mode
The documented route uses Settings and Accessibility or Captions, depending on the device. Inspect Captions mode and read its choices.
On replay requires supported instant-replay content. On mute is not offered on every Roku. Keep those qualifications with any comparison rather than instructing everyone to select a missing mode.
Test the selected trigger
For a conditional mode, perform the supported action on the same reference and observe whether captions appear. For always-on viewing, verify the programme text during ordinary playback.
A replay control and a catch-up entitlement are not interchangeable. This test does not create access to an otherwise unavailable past programme.
Check styling and app ownership
Where the app uses Roku caption settings, inspect text, background and window preferences from the normal seating position. A preview shows a style example, not the actual programme's complete accessibility.
If the app has its own controls, use its supported route and record that boundary.
Verify the next ordinary programme
Roku notes that playback caption changes can be retained. Confirm that the resulting preference suits the next permitted item and household user.
No caption track, Roku or IPTV account was tested here. This is a documented mode-selection workflow, not a guarantee of app behaviour or accessibility conformance.
Describe availability, trigger and rendering separately
A useful report states whether the track is supplied, whether the chosen replay or mute condition was met, and whether the text rendered. If text appears but is hard to read, that is a style/readability result. If the track is absent, changing font size is irrelevant. Keep the exact app, programme and mode in the report so support can distinguish content inventory from a conditional activation issue and from a player-specific renderer that ignores system controls. Use the same programme and edition for the trigger comparison; another episode can have a different supplied track and cannot establish whether the original caption condition worked.
Sources and scope
Scope notes distinguish published documentation, supplied information and editorial methods. They do not report a hands-on service test.
