PayPal appears to be having an issue delaying their ability to complete payments in a timely fashion:
We are aware of delays w/ payments not showing for 4-5 hours. Teams are working to fix asap. Apologies for any inconvenience this may cause.
Seller reports indicate affected payments may not even appear in your PayPal transaction history, which also means they would not appear in your E-junkie Transaction Log. We depend on PayPal IPN (Instant Payment Notification) to receive order details back from them along with confirmation of completed payment. Until we receive an IPN from PayPal for a given order, our system has no way of knowing the order was actually placed and thus cannot process it for you (issue links, send emails, log the order details).
You may wish to use the "Send Free Dowload Link/Code" function in your E-junkie Seller Admin to fulfill affected orders manually for buyer satisfaction, though the nature of this problem at PayPal's end makes it difficult-to-impossible to confirm whether anyone contacting you actually paid at all. Moreover, without your Transaction ID from PayPal, you won't be able to enter that in Seller Admin > Block Buyers / Transactions to prevent us from issuing another link once PayPal finally completes their payment and notifies us of that, though you can enter the buyer's email there and hope that matches the PayPal Email they'd used for checkout.
