Hi Jesse
Thank you for your reply.
I've read the instructions but can't find where in the product-grid-item.liquid file for the "React theme" to put the code for "OPTIONAL STEP 3; Add the star ratings badge to your product listings".
I can't "find the place where each product is rendered" in the "React theme" code as it doesn't look the same as the sample code.
I've added it on line 28, but as the badge is unavailable I can't see if it's installed correctly or not.
Do you have any idea where to put it?
