If you've only just created your catalog, it can take up to a few minutes for all the products in your catalog to get updated on Facebook
Time taken by Socioh also depends on the number of products selected.
In the event that you can't see products on your catalog, please...
give it a few minutes (10 - 15 at most).
refresh both the Socioh and Facebook page (Command + R / CTRL + R).
If you still can't see any products in your catalog, please use the in-app chat on your dashboard to get in touch with us and we'll take a look at it right away.
