We use the paypal add-on and everything was working. Already tried purchases etc. I did not make any changes to it and now i get the error "playfab not authorized to perform action on given paypal account".
I even tried to remove the playfab api in my paypal account and added it again - still not working. Since Paypal obviously gives playfab the permission, is there any bug on your side?
Please help asap. thanks
