I looked everywhere and found this tentative solution: https://community.shopify.com/c/technical-q-a/custom-pixel-checkout-completed-event-not-triggered-after-first/m-p/3043017/highlight/true#M188828

I am waiting till this works and can confirm the fix, but even if it does, why is this something I have to do?

Is it because of a certain checkout page type?

I’m using one-page

Please help me :slightly_smiling_face:
