OfferUp used to actually be functional. Ever since they acquired LetGo and did all of the updates, it barely works. I sold an item and shipped it right away. I kept getting messages to hurry up and send the package or they would cancel the order and I would not get paid. Tracking on the OfferUp app shows the item was delivered. They still canceled the order. I've been going back and forth with customer support and they keep saying they corrected the problem. I still haven't gotten my money.
