This plugin will hide the WooCommerce “Update Cart” button and reload the quantity changes dynamic over jQuery. You don’t need this extra click anymore!
This Plugin is based on a posting on StackExchange related to WordPress developers. I modified the basic concept and created a plugin out of it that WordPress users with less experience in PHP can integrate this function easily without destroying their functions.php file.
There are no options. Just activate the plugin and it will work.
Please note: Since WooCommerce introduced block-based templates, this plugin only works when you are using the classic WooCommerce cart shortcode <code>[woocommerce_cart]</code> added to a page. It is not needed when using the WooCommerce Cart Block.

<ul>
<li>This plugin requires WordPress 4.9 or greater</li>
