Open Shopify's analytics tab and ask it "what's driving revenue right now" and you'll get an answer. It's just the wrong one. You'll see Online Store, POS, maybe a marketplace channel if you sell there. What you won't see is Meta vs. Google vs. email vs. that TikTok creator who posted about you last Tuesday. If you're trying to figure out how to track Shopify revenue by marketing channel, the native reports were never built to answer that question.
