For anyone who is getting the Thank you for your payment! Unfortunately your payment has not yet been fully processed, and you are not yet registered to enter the course "XXXXX". Please try continuing to the course in a few seconds, but if you continue to have trouble then please alert the Teacher or the site administrator
message I did read a forum communication that there can be a slight delay with paypal. This is the reason why if the students leaves it a few seconds before they select the Continue button they will gain access to the course.
Having done extensive testing I have discovered if you leave it a few seconds before you select the continue button this works every time.
Maybe an idea to change the wording explaining this to the student.
Anyway hope this helps.
