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

Which claim requirement was unclear?
What receipt instruction needed explanation?
What example 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: volunteers cannot identify eligible travel items.
2. An unclear receipt instruction identifies ambiguity about evidence required for an approved reimbursement. Explain verified requirements while minimizing personal details and avoiding any request to upload actual receipts here.
3. Turn the requested improvement into a testable next step. One illustrative action is: provide approved example claims.
