Hello,

For the GTIN, ISBN, MPN issue, you can use this plugin: https://wordpress.org/plugins/product-gtin-ean-upc-isbn-for-woocommerce/

And after adding the GTIN using the plugin, please add the filter given below in your theme’s functions.php file:

add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
	global $product;
	$entity['gtin8'] = $product->get_meta( '_wpm_gtin_code' );
	return $entity;
});

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.

Thank you.
