I’m getting the following error when I try to pay via Paypal. Credit card checkout via PayPal Card Processing works fine. But once that’s been done the same customer cannot purchase the same product using Paypal due to this error. I’m not sure how to get a unique invoice ID to be issued during the transaction?
Thanks in advance,
