Instagram Shopping is not automatically updated all of my most recent products

[surfgems]

About a month ago, I set up Instagram shopping through the Commerce Manager, with the Meta Business Suite to automatically update inventory on IG and FB from my Shopify store. All of my inventory was showing up on IG and Facebook stores. However I just launched many new products in several collection on my Shopify store, and none of them are showing up on IG shopping, although the new items do appear to be on facebook shopping. 

Also it seems like there should be an option on my IG to:

"

1. Using Instagram, open your business profile options and then go to the Settings section.
2. Tap Business > Shopping, and then confirm your Facebook account.
3. Select the product catalog that you want to connect.
4. Tap Done. "

However when I click into Shopping, there is no option to confirm my Facebook account. I am not even sure if this is the root of the issue. But either way, non of my new products are showing up on IG.

Pls Help!
