Sauce Embeds are designed to be curated - as it's likely not all of your Instagram posts are intended to be Shoppable. For Sauce Users who have an Instagram Shop and are already adding Product Tags within Instagram, you have the option to have these Media automatically brought into your Sauce Media Library.
The "Auto add" feature can be enabled or disabled via a Toggle within the Media Library, specifically the 'Instagram' tab, as shown below.
Note that you will need to be on a plan which supports this feature.
When is my Tagged Instagram media brought into Sauce?
Your Tagged Instagram media will be fetched once daily, and thus may take up to 24 hours to appear after having been tagged within your Instagram account.
How does this compare to the Live Feed feature?
The key difference is that the Live Feed feature is not Shoppable, in that it does not take into account your Product Tags, nor does it allow you to add Tags within Sauce.
