Star Ratings not showing on product page

Hi there,

I’m using the theme “Taste” and have added Klaviyo reviews to our product pages. Both the Star Rating and the Feature Reviews section.

I have one test review in the account and when I’m in “Customise theme” the star rating comes through and so does the featured review; however when I go to my live site after I've published the changes there are no reviews.

I’ve checked all my settings and have checked multiple forums for help but no luck so far!

Thanks
