 * Hi,
 * We use GTIN field from Rankmath Plugin. There is no option to map it for use 
   with the review opt-in.
 * Any information on this?
 * Best Regards

 * Hello [@nikeri](https://wordpress.org/support/users/nikeri/),
 * Thanks for reaching out.
 * If you added the GTIN using Rank Math, it should automatically migrate into the
   native WooCommerce GTIN field when you update your plugin or use their database
   tool. As noted in their documentation:
 * > Source: [https://rankmath.com/kb/gtin-mpn-woocommerce/#add-global-identifier](https://rankmath.com/kb/gtin-mpn-woocommerce/#add-global-identifier)
   >  **Note:** If you previously used Rank Math to add the GTIN code to your product,
   > the data will automatically migrate to this WooCommerce field when you update
   > your plugin or use the database tool.
 * Our plugin uses the **native GTIN field from WooCommerce**, so as long as Rank
   Math correctly populates this field, the review opt-in should work as expected.
 * Please ensure you’re running the latest version of Rank Math and check if the
   GTIN values are stored in the native WooCommerce field. If you continue to experience
   issues, feel free to reach out for further assistance!
 * Best Regards

 * Hi [@nikeri](https://wordpress.org/support/users/nikeri/),
 * I hope you’re doing well!
 * Just following up on your inquiry regarding the GTIN field and its use with the
   review opt-in. As mentioned earlier, if you’re using Rank Math to add the GTIN,
   it should seamlessly migrate into the native WooCommerce GTIN field during plugin
   updates or through their database tool.
 * To recap:
    - Ensure you’re using the latest version of Rank Math.
    - Confirm that the GTIN values are correctly populated in the WooCommerce GTIN
      field.
    - The review opt-in should work as expected as long as the GTIN is stored correctly
      in this field.
 * If the issue persists, please let me know, and I’d be happy to assist further!
 * Best regards

 * I have installed the **Merchant Center Reviews for WooCommerce plugin (Version
   1.0.8)** together with **WooCommerce Version 10.1.2**.
 * After placing an order, the opt-in dialog for collecting reviews is displayed
   correctly. However, in the generated code the product information is incomplete–
   I only see:
 * `"products":[{"identifier_exists":false}]`
 * It seems that the product identifiers (SKU) are not being passed to the `products`
   array, only `identifier_exists:false`.
 * For the ordered product, in the database table **`wc_product_meta_lookup`**, 
   the **`sku`** field contains the correct value.
 * Could you please advise how to configure the plugin so that proper product data(
   SKU) is sent to Merchant Center in the review opt-in code?
