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

Which preference was hard to express?
What option description was unclear?
What information would help choose?

Author notes / illustrative keys where applicable:
1. A preference users cannot express identifies a gap between desired recurring-order choices and available controls. Confirm actual options before promising customization.
2. An unclear option description reveals where recurring-order choices fail to explain their actual consequence. Clarify verified distinctions and applicable conditions, without promising unsupported customization or assuming an option is available to every subscriber.
3. Information needed to choose identifies an option consequence or condition requiring explanation. Use verified distinctions without implying the same choices are available to every subscriber.
