Hi Benjit,
Thanks for you reply. I will open a support ticket.
Please try switching between different shipping methods, the radio button of the selected method remains unchecked. This seems like a visual bug because the cart total is updated normally, just the button is left unchecked. If the button is clicked a second time however, only then it becomes checked.
Steps to reproduce: While on the checkout page, switch between different shipping methods. As you will see, the new method updates the order details (even if it doesn’t add any extra costs) but the shipping method remains unchecked until it is clicked a second time.
