To clear tickets incorrectly marked as 'Attended' from a play, you perform the following steps:
If a mistake is made in setting attendance, attendance for the entire performance (or optionally, specific tickets) can be cleared.
If you set a time limit in a watch window, and somebody exceeds it, so that that cannot see their event. Clear their attendance flag and then they can re-watch the item. |
The tickets for that performance are displayed in the attendance list.
