Hi everyone,
I have the same issue with Paypal which is blocked at 80% with the module OnePage Supercheckout by Knowband, have you @efer33 solved this problem or try the solution provided by @salud marco ?
In the module parameters, in the "log in" tab, they propose to follow 17 steps, and connect to this website https://developer.paypal.com/developer/applications/ to ask an app review.
It should take 7-10 days to review according to this website.
Does anybody tried this?
Thank you so much !
