Hello! Could you please help me to understand why my experiment is tracking though I stopped it?

What is your last screen shot from? For a client-side experiment, there may be connection or caching issues that mean that some users are still entering the experiment.

It’s logging that we added to the

trackingCallback

inside Growthbook instance creation in our React app.

Is the feature rule change saved and is the React app you're testing in able to receive updates from the server?

Yes, it’s connected and subscribed to changes.
