dear community!
I've encountered an issue while implementing the Conversion API integration on our website to track events and send them directly to Facebook from our server. We're experiencing problems specifically with the Purchase event.
What's particularly strange is that all event data appears correctly in the Ad Campaign table, except for the Purchase event. I've conducted test events, verified them in the Payload Helper, and everything appears to be configured correctly for optimization. However, optimization for the Purchase event continues to not work and seems to be completely ignored.
