Out-of-stock products/variants are still showing

After enabling the Out-of-stock display options in our app admin (please see this feature here) to hide the unavailable products/variants, you might still see them showing up.

Kindly be advised that in your Shopify admin, if you set the inventory for a product as Continue selling when out of stock, the out-of-stock products/variants will still be shown. Then please make sure you set it as Stop selling when out of stock if you would like to hide the unavailable product. 

All you need to do is go to your Shopify admin > Products > Inventory > select the products/variants > More actions and choose Stop selling when out of stock.
