Hello, ProdbyDaan,
We would like to inform you that the patch in question only affects files within our theme, as evidenced by the following screenshot: https://prnt.sc/LR3keECAJDzP. It does not impact the files of other themes and is not implemented when a different theme is activated.
In the most recent update, WooCommerce has made modifications to the cart-shipping.php file. Our patch is designed to incorporate these changes accordingly. When the Storefront theme is active, the cart-shipping.php file is sourced directly from the WooCommerce plugin, rather than from our theme. Consequently, our response remains consistent: the issue you are experiencing originates from the WooCommerce plugin itself.
We trust that our explanation has been comprehensive. Should you require further assistance, we recommend reaching out to the WooCommerce support team, as it appears that their recent update may be the cause of the changes observed on your website, as well as for other users utilizing WooCommerce.
Best Regards,
The 8Theme Team
