Hello,
Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.
You can fix this warning by adding GTIN 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/
And you can use the bulk editing option to directly add the focus keyword to your product from the product lists. Please navigate to WP Dashboard > Rank Math > Titles & Meta > Products and makes sure that the Bulk Editing Option is Enabled.

Now go to WP Dashboard > Products > All Products and here you will see a column named SEO Details. Click on the edit icon and you will get an option to insert the focus keyword.

Hope this helps and let us know if you need any further assistance.
Thanks

Hello,
Thank you for keeping in touch with us.
Adding Keywords to your content should be unique and would depend on the content on each pages/posts so you may need to individually set this.
We have this custom code that retrieves your product’s title and set it as the product’s keyword. You need to insert this code in your theme’s functions.php file:
function update_focus_keywords() {
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'product' /* post types: post, page, product */
));
foreach($posts as $p){
update_post_meta($p->ID,'rank_math_focus_keyword',strtolower(get_the_title($p->ID)));
}
}
add_action( 'init', 'update_focus_keywords' );
See if this helps you with your issue.

Since these are just warnings, you can simply ignore these if not applicable to your product.
