Fix Shopify Conversion Tracking

My Shopify store’s conversion events are simply not firing, and I’ve traced the root cause to the basket state: it refuses to update when shoppers add or remove products. Because the cart value stays static, none of my purchase or “add-to-cart” tags ever move past the trigger stage, so Google Analytics 4, Google Tag Manager and my Meta Pixel all show zero events.

Here’s the help I need:
• Diagnose why the basket fails to refresh in real time—theme code, AJAX cart, or any conflicting app.
• Repair the cart logic so quantity, price and line-item data update instantly across the site.
• Verify that GA4, GTM and Meta Pixel (or your recommended equivalents) receive the correct add_to_cart and purchase events once the cart works.
• Supply a quick test plan (Preview/Debug or Facebook Test Events) so I can confirm everything is firing before we push live.

You’ll have collaborator access to the theme and my tag containers. Once cart updates correctly and the key events show in their respective dashboards, the job is complete.
