Having a few issues with PayPal Express and CT Pro 2.2.9:
Upon checking out to PayPal and clicking PayPal's "Cancel and Return to Store" link, the user is taken back to the URL in the checkout form's return parameter. Does PayPal Express not make use of the failed_redirect parameter?
Upon a successful PayPal Express transaction, CT's cart isn't emptied? I have tried this method (http://cartthrob.com/forums/viewthread/7557/), however, the clear cart tag, although in the if authorized conditional, empties the cart on payment failure also.
