I am using the Loox app. When I am customizing the theme I can see my Star Rating properly but when I see the preview of my store, I am unable to see my Star Rating. Please help ..!!!
Hey,
Rotem from the Loox team here 
Loox Rating Widget only appears on the live store for products with at least one approved review.
The theme editor widget is a sample, displaying a fictional number of ratings.
Once reviews are added to your Loox account, ratings will automatically appear on your live pages.
In any case, you are welcome to contact our support team and we’d be happy to help!
