Hi I have a little problem with Paypal Express Checkout plugin on nopcommerce ver 3.8.

If in the process of payment the customer changes the Billing address and introduces an invalid address where I can not sell my products my website detects the error but if the custormer clicks on Confirmation button, the money transfer is realized even if the website returns error.

Please can you help me?

thank you.
