We have a Shopify products collection with "Best-selling" sorting.
When I visit this collection on our site, I notice that the order does not respect the sales volume of the products in the collection, at all. Which is a shame for our visitors.
I checked in the Shopify admin to be sure it wasn't a display issue, the order is exactly the same.
Here is an overview of the collection in question. In red, I added the quantities actually sold, since the store opened (CSV export of our sales).
I am extremely surprised. Can you explain to me how this is possible?
