I am attempting to list my tickets for sale. My seats are on the East Side Upper level. The selection for this area is not available. It looks like the seating chart is set up for a different event.
Stubhub has a special link for you to complete if there is an error with the seating for an event
It generally takes them 1-2 days to fix but I suspect with all of the time being spent on confiming cancelled, postponed or rescheduled events it may take a little longer.
