Purchase/BeginCheckout Event Data Loss – Facebook CAPI (WooCommerce)

Hi,
I implemented Facebook CAPIs in a Woccommerce site with Consent Mode Enabled

Almost all events are ok.

Only “Purchase” and “BeginCheckout” are tracked much less (about -50%) by server than browser.

In debug everything seems ok.
I’m trying to use DataTag Stape to replace GA4 client but I don’t see any improvements.

I can’t find the problem.

Experiences or suggestions?

Thanks

I ask you to show us some screenshots of how you set everything up so that we can have a clearer vision of your problem.
