 * When using checkoutWc, the summary plugin returns the following error:
   Uncaught
   TypeError (in promise): o.wc_checkout_form.blockOnSubmit is not a functionin 
   Object.sumupCheckoutSubmit (sumup-process-checkout.min.js?ver=2.4.2:1:494)in 
   HTMLFormElement.initSubmitProcess (sumup-process-checkout.min.js?ver=2.4.2:1:

 * Would there be any provisional solution?
