I found a lovely snippet-turned-plugin on this thread:
Event Ticket: List of All RSVPs (Attendees)
I really want to be able to use this, but there’s a problem with its math calculation. It’s adding up all the global stock for each ticket variation, so the “Remaining” column shows multiples of the actual number of available tickets.
(I realize the topic in question is now a year old, and was already bordering on being outside the scope of support, but it would be so helpful if this could be fixed!)
