We are totally stumped! We have customers who incur multiple charges and never have their orders completed. There doesn't seem to be any rhyme or reason to the cause. In fact, we just had a customer who was logged out (and charged). The customer immediately logged back in, and the order was successful (charged again). We have determined that the session of affected customers seems to be newly established upon redirect from Payflow. We cannot figure out the cause. We cannot reproduce this in development, no matter how many times I've tried. Please help!
