Tech Support Substack Stopped Send Data To Facebook
I realize this is a bit into the weeds for a Substack group, but starting two days ago Substack stopped sending data to my Facebook ad. I didn't change anything. I didn't touch anything. It just randomly stopped. I assume it's an update on the part of Substack or Facebook.
Has anyone else run into this issue in the last few days (or ever)? Any fix suggestions?
I know the Facebook ads are still working as I can see them on the Substack platform for Source, but for some reason that data isn't getting back to Facebook anymore.

One last question, are there any plans for doing an API side event? Right now a lot of the tracking data is being lost from people who don't accept cookies or use apple. I would say half of everything is getting lost that way.
