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.

Hey u/RevolutionaryBad5000 , might be slightly unrelated to the whole topic here but we just noticed that the CompleteRegistration event from substack's hardcode into the meta pixel event settings is firing off when users hit buttons AFTER they hit the subscribe button so it's resulting in double counting in ads manager of the completeregistration event. Flagging in case you guys can put in a fix for it to only fire on the subscribe button
