After following with judge.me and adding the below code all errors except “review” have gone even though product has review. Is that normal? Please check.
"add_filter('rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
global $post;
$entity['@id'] = get_the_permalink( $post );
return $entity;
}); "

Hello,
Rank Math takes the schema data from your product pages automatically and turns it into Schema-ready content. Likewise, the review fields are taken from your actual product reviews. Please add some author review to get rid of the review
warning.
You can fix the SKU and availability issue easily as well:
For the GTIN, ISBN, MPN issue, you can fix it by adding that to your products using the custom product attribute feature in WooCommere or you can use this plugin: https://wordpress.org/plugins/product-gtin-ean-upc-isbn-for-woocommerce/
For the priceValidUntil warning, you have to either ignore that or add a sale price with validity to get rid of it: https://i.rankmath.com/cMqAAH
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
