On October 19 we have noticed an issue with Paypal payment notification system.
Normally, Paypal notifies us about a successful payment within 30 seconds after payment. However, today, some notifications never come to our billing platform. From our initial investigation it looks like approximately 3-4% of all Paypal payments are affected.
If your payment is affected, please submit a support ticket with your Paypal Transaction ID, and we will manually credit the payment for you.
In the meantime, we are getting in touch with Paypal to get this resolved as soon as possible.
