Auto coupon with one payment method don’t works fine in checkout

Really, when I select another payment method and click in checkout, this message appear and it’s impossible to buy:

“Sorry, it appears that the coupon “name of coupon” is invalid – it has been removed from your order.”

Ckeckout page is reloaded without the discount, but if I click in checkout button the page it’s loaded again with the same message.

Append this snippet to functions.php:

//Update the cart preview when payment method is changed by the customer
add_action( 'woocommerce_review_order_after_submit' , function () {
    ?><script type="text/javascript">
        jQuery(document).ready(function($){
            $(document.body).on('change', 'input[name="payment_method"]', function() {
                $('body').trigger('update_checkout');
                //$.ajax( $fragment_refresh );
            });
        });
    </script><?php 
} );

Thanks for your reply. I put the code and it seems to reload the section of the checkout but when I change the payment method it continues to subtract the value of the coupon.

Please send me your coupon settings and an url to reproduce the issue.

Url is: https://www.chinarodriguez.com/crea-tu-propia-marca/

You have to click on “Realizar tu pago” button to add the product to cart and go to checkout page.

Coupon settings:

Percentage discount
Coupon amount: 20
Product #2392
Apply without message

Thanks!

What is the coupon code, please? If you don’t want to publish it here, you can send it to admin at soft79.nl.

There are some errors on your page as well:
“POST https://api.mercadopago.com/modules/tracking/checkout?token=&referer=https%3A//www.chinarodriguez.com 400 (Bad Request)”

but probably not related.

Solved. The user’s functions.php had a conflicting snippet that disabled coupons on cart/checkout page.
