If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which term was captioned incorrectly?
When did captions obscure useful content?
What transcript improvement would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: technical terms are transcribed inconsistently.
2. The obscured content identifies an interaction between caption placement and the material being explained. Review that specific segment and alternatives; reported interference does not establish caption accuracy or overall accessibility.
3. Turn the requested improvement into a testable next step. One illustrative action is: review a glossary against the captions.
