I have an issue with my Facebook Pixel since it is not tracking "Purchase" und "Add-to-cart" events at all. I contacted Shopify and Facebook support but they were not much of a help..
For the integration I used the official Facebook integration setup and so far "View Content" and "Page View Events" are tracked properly. The check-out code is not changed. How can it be that it doesn't track it properly?? Any suggestions? Shop link
