Hi, if I register on the website, and I go to My Account and Select Payment methods, there is no option for me to select a payment method to assign to my account.
Under My Addresses if I enter the address there on registration, I still have to enter it on checkout.
Under Account Details, when registering, if I enter my name and surname, it still asks me for my name on the Profile Details Page.
Woocommerce does not provide the option to assign a payment of the account by default. You will have to find a plugin. We have not tested any plugins that is why we cannot recommend any.
