PRODUCT Description Not Use Template

Hello,

Thank you for getting in touch with us.

This is the order we follow to generate meta descriptions for WooCommerce product:
1. Content from SEO Description field
If that is missing, then:
2. WooCommerce Excerpt or Product Short Description
If that is missing, then:
3. Template From General Settings in WordPress Dashboard > Rank Math > Titles & Meta > Products
If that is missing, then:
4. Auto generated Content from the product page

You can add the following filter to your theme functions.php to override WC excerpt and use the Global template

/**
 * Use the Description from Global Setting, if the description is missing in the Post metabox
 */
add_action( 'rank_math/frontend/description', function( $description ) {
 global $post;
 $desc = RankMath\Post::get_meta( 'description', $post->ID );

 if ( is_product()) {
 $desc = RankMath\Helper::get_settings( "titles.pt_{$post->post_type}_description" );
 if ( $desc ) {
 return RankMath\Helper::replace_vars( $desc, $post );
 }
 }

 return $description;
});

Hope that helps. If you have any further question(s), please let us know. Thank you.
