Hi @mrclayton,
oh sorry.The error message pops if customers want to pay with credit card. SOFORT seems to work just fine.
I was experiencing this error while I didn’t have any 3rd party plugins for checkout but now I tried it also with an active 3rd party plugin. Both instances produce this error.
I deactivated the plugin but I get the same error message. Other payment methods like paypal work just fine without the billing phone.
I found the same error in the support section of this plugin “WooCommerce Stripe Payment Gateway”. It seems that they adjusted the plugin for that functionality.
Best regards.
