PayPal has posted a system status alert confirming some IPNs may be delayed. We depend on IPN (Instant Payment Notification) to receive order data back from PayPal and confirm completed payment, so any IPN delays would affect how quickly we can process orders for you -- i.e., notify you of a sale, log the transaction, send thank-you emails, issue download links or purchased PIN/key/license codes, and forward order details to any custom/third-party Integration URLs you may have set up.
You can reassure concerned buyers that their download link or any codes they'd purchased will be sent as soon as PayPal catches up with their delay.
You may also choose to satisfy impatient buyers manually by using your Seller Admin > "Send free download link / code". In that case, you can also prevent an additional link/code from being issued to them when the IPN finally arrives, by entering your Transaction ID for their payment (which you can find in your PayPal account history or receipt email) in your Seller Admin > Block Transactions screen -- in this case, bear in mind that means we would not process the order at all, including not recording the order in your E-junkie Transaction Log, etc.
