I have created a "Rest Api" and stored AT for Austria here. Then I wanted to test the payment process with my private PaPyl account. The forwarding works, but Pappal opens an English login window. Now I use my saved access data and always get an error message. The login details are incorrect, says Papal. But these are correct. I keep turning these. Could I have done something wrong when creating the RestApi? Other Austrian Papal accounts cannot log in either.
