2 days ago we started getting a large number of customer complaints from people who had subscribed to our service via PayPal subscribe button but we had not activated their subscription. We checked our logs and paypal.com activity and ran some tests and confirmed that payment is being taken by PayPal, emails are sent from PayPal to users, but IPNs for MANY transactions are not be generated at all. They are never sent to our server, and they never show up in the IPN history page. Searching the IPN history for a transaction that we just made where payment was taken, which does show up in the activity page, does not show up at all in the IPN history page, even 24 hours later. We have a typical number of subscriptions naturally expiring every day, and in the last 24h that number has increased by over 400% as IPNs are also not being generated for recurring payment transactions, and our system has revoked access for some of these users based on non-payment. We have an open case with Merchant Technical Support who have not responded in 32 hours, and PayPal Business support who say this probably won't be looked at until next week. Can anyone confirm if a similar problem is happening, maybe undetected? Is there any way to escalate to have MTS actually look at our case?
