There were some issues with the new Beta version. I tested and fixed the problem, so everything should be good right now. I had to clear the current bids from the auction books.
Also because some asked for it, the delay added to the last bid is 12 hours instead of 24 hours.
If you sell inventory items, all processing (transmission of items and payment) is done automatically on the backend, and you don’t have to do it manually. If you sell another type of items, then you will have to contact the buyer .
