According to https://docs.drupalcommerce.org/commerce2/user-guide/checkout/allow-register-at-checkout the 'Login or continue as guest' checkout pane should have an option 'Allow registration'. In my environment with the latest commerce 2.12 however I can't find this option. Why is this option not shown?
I don't want to allow registrations on my site and only allow guest checkout. How can I achieve this?
