I have an unresolved online sale that is not on the Registrant tab of my event, but the event is at capacity without including those tickets. After completing an unresolved online sale my event is over capacity. The remaining capacity of my event is not including my unresolved online sales.
We are currently evaluating this issue and will update this article when we have more information.
