I enabled product recommendations on my product page in Shopify and if I click on a product from the collection, all is fine, and the url is wwww.../collections/frontpage/products/... And I can see the recommendations. But when I click on a product FROM THE RECOMMENDATIONS, then there are no recommendations on the product page and the url is an other. www.../products/.... When I change the url to the other from: When I click on the same product from the collection, then the recommendations are there.
In short: If I click on the product from recommendations, there are no more recommendations, because it opens an other URL. Product is the same, but not the url, and that is the reason why the recommendations are not shown. (I think)
