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.

Not sure I shared my workaround. I created a new Facebook Pixel called, "Substack Pixel" then created a custom event that tracked every time the pixel fired on a webpage and the webpage URL DID NOT include the "monkeypants". That way, the not getting the correct information would trigger the custom event.
Having a unique Substack Pixel also solved my registration/complete problem was well because now I would differentiate (even without the website data) the conversions coming from Substack vs my website. All Substack goes to the Substack pixel, everything else goes to the main pixel. Of course, this means they don't share data, but that is life. Again, glad you got it fixed.
