The WooCommerce Square payment form on the checkout page only shows 12 digits of the card number to the customer as they’re entering in their card info. A customer has complained and we verified the issue exists on mobile phones. We are still getting sales because customers have found a workaround by entering all digits even though it doesn’t show them, scanning their credit card or flipping there phone horizontal. However, some customers have gotten stuck at this point since only 12 digits are shown and contacted us. Please let us know when you can resolve this issue.
P.S. We reported this issue to WooCommerce Square developers and they said it’s something to do with the Jevelin theme overriding the checkout page, I attached their response.
I hope you are well today and thank you for your question.
It seems the woocommerce-square plugin that you are using on your website is causing the issue so could you please try temporarily deactivating the plugin?
