I’ve responded to your support request. For general info – the issue appears to be related to PayPal problems which currently is very slow and has extremely long response times. The payment integration works by us first sending you, the buyer, to PayPal via a redirect link to your browser. You then pay to PayPal. We then do nothing until our server gets a ‘call back’ from the PayPal server, upon which time we credit the account. In this case, the ‘call back’ appears to have been delayed by PayPal for almost 12 hours!
