SUMMARY:Privacy Test Pages — Recurrence With Unsupported Part
DESCRIPTION:Monthly on the last Monday using BYSETPOS. The parser drops BYSETPOS silently\, so the editor opens with a plain monthly Monday recurrence (no user-visible warning); the m_ics_calendar_unsupported_rrule pixel fires in the background.
LOCATION:Privacy Test Pages
RRULE:FREQ=MONTHLY;BYDAY=MO;BYSETPOS=-1;COUNT=6
