Did Shopify push changes to the Checkout in the last 24 hours? All if not most of the products in checkout are being flagged and a pop-up with “Inventory Issues.” We do have a fulfillment constraint function in place however this has been in place for the last 1-2 months with no issue.

We just figured it out. A rogue location was added in by another person and was not accounted for in the Shopify Function logic.

Checkout - "Inventory Issues"
