We are having problems with clients paying with PayPal. They get the confirmation email from PayPal but our site is not getting any confirmation that the payment was completed.
Because of this the client does not get an email from us, their order stays at 'Awaiting Payment' and their download link is not enabling.
Our test team has verified that they are waiting for PayPal to return them to the site but still the order status is not completed with payment processed.
