Hello! I am trying to pipe AB test data to Mixpanel by sending a log event in the trackingCallback located in my AppDelegate (I am using Swift). The only issue is that I want this log event to only be fired when a user FIRST joins the test, not every single time a user encounters a feature in the app that triggers a test. I have tried putting an if statement: if (!experimentResult.inExperiment), but that always returns true obviously because the callback seems to only be called once the user has already been put in the test. Can someone please help me?
