I'm still seeing the status as "Waiting for Payment" on a domain, even though I've already paid for it via PayPal. That usually changes after a few seconds, but it's been a few minutes and it still says it's waiting for payment.
We had a problem with Paypal earlier today where Paypal would not verify payments we received from our customers. We have since resolved this, so your order should have been processed already. We apologize for any inconvenience this problem might have caused you.
Still "waiting for payment" after many minutes.
