It's still very early and today is eBay's maintenance day too, so many things go a little awry or delayed, whilst those in eBay Towers HQ CaliforNIA are tweaking and installing new systems. late yesterday evening i or the early hours of the morning over there in the States.
Try again a little late on today.
Also be aware, if it is an unusual pattern for you to sell a high value item, the payout can be held for longer before release. It's a standard security measure for your account and the buyer.
