The system for payouts has had a major change.
Was this a collection item, and you decided to deliver it yourself? Then message the buyer to look for the 6 digit QR code found either in eBay emails / message/ order details. They need to send those number to you for you to manually enter the numbers in the order details to the left of ..... Confirm Collection.
If this was an item that should have been posted now with no tracking to prove delivery, you will have to wait 14 days for that payout.
