If you received Sale Notification emails from us and/or see the affected orders listed in your E-junkie Transaction Log, that confirms we received IPN from PayPal confirming those completed payments and processed those orders for you accordingly (issued links, sent emails, logged the order details, and forwarded the order data to any custom/third-party integration URLs you may have set up).
Payment receipt emails are sent from PayPal's end and thus are unfortunately beyond our control or scrutiny, but it sounds like PayPal's issues last night delayed their ability to send those out in a timely fashion.
