Fix Shopify Meta Pixel Tracking

My Shopify store is already linked to Meta Ads and the standard PageView and ViewContent events report perfectly in both browser and server-side modes. The problem is that Add to Cart, Initiate Checkout and Purchase only appear as server events and sit at 0.0/10 match quality with no corresponding browser data.

What I have ruled out so far:
– Data sharing level is set to “Maximum” through Shopify’s Facebook & Instagram channel.
– I confirmed no cookie-consent app is blocking scripts.
– These events rely purely on Shopify’s built-in tracking, not custom code, and the theme hasn’t been modified or had new apps installed recently.

You will receive collaborator access to Shopify plus the Meta Events Manager for Pixel ID NC-1. I need you to pinpoint why the browser events are missing—whether it’s a duplicate base pixel snippet, misplaced code, an API configuration conflict, or something else—and implement the fix so that Add to Cart, Initiate Checkout and Purchase fire in the browser with normal match quality.

Deliverable:
• All three events appearing in Events Manager with healthy (green) browser-side activity, matching against test purchases.

Please include a flat quote and expected turnaround time; I’m ready to give access as soon as we agree.
