I am not sure if its just me but when a seller registers, they provide an email address. this email address is used as the paypal address as well. However, if they change the paypal email address in settings then this is not being updated in wp users. There is also no way to change the email address? Is there a way to use one email address for contact another for paypal? Could this be put into the next update?
I have the same problem. The paypal email should be included in the registration form when a user signs up (customer and seller, just in case a customer changes to a seller later). If it is included with the registration form, they can't skip it and the site owner will be assured there are no errors at checkout.
