After testing (thanks for the link @Lilly_S) I can confirm that the poll edit window mins appears to apply to site staff in addition to regular users. Further, the poll edit window mins appears to prevent removal of polls in addition to edits. I think we should:
- Ensure that staff are not affected by the
poll edit window minssite setting. - Ensure that
poll edit window minsonly applies to edits, so regular users can remove polls even after the poll edit window.
