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

Which field purpose was unclear?
What visibility information was missing?
What choice 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: members cannot tell which fields appear in the directory.
2. Missing visibility information affects whether members can make an informed choice about optional profile fields. Explain actual audiences and controls before collection without assuming they want public directory exposure.
3. Turn the requested improvement into a testable next step. One illustrative action is: explain visibility before collecting profile information.
