try to remove your
credit card details
maybe the app is better.. but tryign to remove card details from your "shop account" when you haven't opened a shop account.. is a PITA.
only way is to delete the "account", and hope they delete your credit card data after 30 days...
it's the auto-fill of Ccard info on a new site that uses SHOP, because you previously bought something on a different site that processed through SHOP in the background, that annoyed me (not having opened a SHOP account or allowed savign of card data)... I don't want SHOP prefilling my card data when i haven't given them permission to do so, across vaqrious unconnected vendors, and i couldn't remove my card data from them
