Ticket for the next show (Washington) are surprisingly selling like hot cakes on Stubhub

Not doing that well on Ticketmaster due to many people refunding their tickets because of the rescheduling, but their map might be frozen and that's why it shows up so many tickets left.
I doubt tickets would literally be selling so fast on Stubhub, but nobody would look up for the official ticket seller to purchase them at even lower prices
The show is in 2 days and there are only 360 tickets left for it on Stubhub, there were like 1,500 left only a few days ago, while on Ticketmaster, days go by and ticket sales remain stagnant.
