Are you using elementor ? [yith_ywraq_button_quote] shortcode works in premium version only. do you have free or premium version? can you try putting shortcode in page or post directly and see if get any result or not? few more details in documentation Make sure you enter the product’s ID with the parameter “product” to link the button to the right product in your WooCommerce. For example: [yith_ywraq_button_quote product="1234"] will let your users add product with ID 1234 to the cart. However, it is not necessary to enter the product ID when using the shortcode on a standard WooCommerce product page, as it will automatically link the button to the product it belongs to.

Hello Alonso, Could you change the template part to this code

<div class="col-6 col-lg-3 mb-5">
<div class="card rounded-lg">
<div class="card-body text-center">
<a rel="nofollow" href="<?php echo esc_url( get_permalink( $product->get_id() ) ); ?>">
<?php echo $product->get_image('woocommerce_thumbnail', array('class' => 'img-fluid')); ?>
</a>
</div>
<div class="card-body pt-0">
<a rel="nofollow" class="card-text" href="<?php the_permalink();?>"><?php echo $product->get_title(); ?> <?php //echo apply_filters( 'woocommerce_short_description', $post->post_excerpt )?></a>

</div>
<div class="card-body border-top d-flex justify-content-between">
<div class="d-flex justify-content-center w-100 flex-column flex-md-row">
<?php echo do_shortcode('[yith_ywraq_button_quote product="' . $product->get_id() . '"]');?>
<?php do_action( 'woocommerce_after_shop_loop_item' );?>
</div>
