Hi ok thankyou for confirming about the code snippet.
I had enabled the reviews ages ago when it was not in merchant center.
In merchant center i have this message…..
Google Customer Reviews has not displayed an opt-in notification to your users in more than 30 days. Make sure your opt-in integration is correct.
I think its all setup in merchant center, i have put my merchant key into the plugin settings in WP.
Heres a thankyou order url…… https://jarlights.co.uk/checkout/order-received/4116/?key=wc_order_599fdee23a30a
Hope you can help and sorry i dont know more.
Thanks
