Shopify Brooklyn. Integration practically at completion. I have a problem with capturing data for Klaviyo from "add to cart" buttons from collection pages (each button has a different id, but the same class. Klaviyo does not foresee this - that was the answer I got from support. From the product pages everything works fine - but here we have all the data at our fingertips. I expect a ready code snippet with an indication where to insert it from someone who has already done this.
