Same issue. Can't use PayPal and can't use iDEAL either. Tried deleting my PayPal from game after getting the 80801 error but now I can't get it back anymore, just gets stuck in an add PayPal method loop everytime. Even when it says that it's added on the Guild Wars 2 website, it's not. Don't have a credit card either, so no way to buy gems rn for me.
