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

Which enrollment step was unclear?
What approval did you need?
What information should appear before booking?

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: learners discover manager approval after choosing dates.
2. Required approval identifies a dependency separate from the enrollment interface itself. Clarify the actual authorization route and timing information, without implying that a submitted request or manager discussion guarantees admission.
3. Turn the requested improvement into a testable next step. One illustrative action is: show approval requirements before date selection.
