... As you told, I am going to test the transaction workflow again with the settings you told me.....but before doing this, I have one question. The field: "Use Stripe Strong Customer Authentication (SCA) is only visible if I choose the Payment Button method: 'Inline Form (Elements)' ......as soon as I choose 'Hosted Checkout' this field disappears ?!?.....question: Why depends the kind of authentication on the way you present the fields on the GUI?
