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

Which suggestion did you expect an update on?
What did the update explain?
What would make the decision clearer?

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: customers see status changes without an explanation.
2. The explanation recalled from an update distinguishes acknowledgment, investigation and a decided change. Align follow-up wording with the actual stage; remembering the message does not prove that a suggestion was implemented.
3. Turn the requested improvement into a testable next step. One illustrative action is: explain the decision and next review point.
