Hello! We are trying to sync our Shopify account to our Klaviyo account to create an automated flow for customer notification when items are out of stock. In order for the Klaviyo Back in Stock code to work, either the Add to Cart button or the Add to Cart form need to be present on the product page. We are using the Working Canopy theme which removes the Add to Cart button when there is no stock. Is there a way we can ensure the out of stock products display a Sold Out button so the Klaviyo code will work?
