Hello @lino76 ,
I’m glad that worked. Thank you for your feedback.
– the error bubble not displayed if the checkbox is not set is probably a styling issue, did you try switching to the default twentynineteen theme ? And deactivating all other plugins ? That would discard a styling conflict.
– the postal code next to the credit card number is redundant at the moment, it is meant to allow extra verification in the future ( set postal code verification in the Stripe options as it is a Stripe element ).
– the mobile style are not ready yet and global styling also need to be improved.
Switching to a custom form to avoid the Checkout redirection was a major step, the style will become more stable in time.
Direct Stripe being free that also allows users to contract a front-end developer to make it all look nice !
