Purchase events not firing in GA4, Google Ads, and Facebook Ads for my Shopify Website

I'm currently dealing with a really confusing problem where 'purchase' events aren't showing up correctly in GA4, Google Ads, and Facebook Ads. 'Add to cart' and 'check out' events are tracking just fine, but 'purchase' events seem to be missing when real customers make a purchase. When I run tests in GTM and Facebook Event Tester, everything looks good and the purchase events fire correctly.

I've double-checked all my settings and configurations, but the issue is still there. Has anyone else run into this or have any ideas on how to fix it? TIA!

Hey there,
I've encountered this issue before. It usually happens when events don't pass through the data layer properly. Relying only on browser-side tracking might miss customer events, especially with ad blockers and the iOS 14 update blocking cookies. Third-party cookies also have limitations. For a more reliable solution, consider setting up server-side tracking via Google Tag Manager on a first-party domain.
