Catalogue IDs do not match the pixel
When the pixel sends a different ID from the product feed, dynamic ads show the wrong items or none at all.
Fashion stores live on Meta catalogue ads and retargeting. That only works when every variant, size and colour is sent with the right product ID, from the browser and the server.
