Problem of acces to CoursePress with Paypal Chained Payments

- Pluggins are updated.
- Subsites sell courses and admin takes a commission for each course sold.
- CoursePress is ok with Paypal express (A student pay and after payment, he can view the course).
CousePress doesn't work when I use Paypal Chained Payments : Student chooses the course, he pay with Paypal (chained), Admin receives commission, and seller receives his $$, mails are ok too :slight_smile:

All is ok but the problem is that once the payment done with confirmation page, student goes on the course and he hasn't access.
Payment is ok (I checked all Paypal accounts) but student doesn't access to the course, the button is always the same, I don't know why ...

Any ideas ?

Thank you in advance
