Another issue for us is we use different experiment id compared with the feature flag id. So I have to change the tracking key in the experiment to use the experiment data. And then the feature flag can’t find the matching experiment id as it’s different. Any solution for this? like manually associate feature flag to experiment.

That's interesting. How does it get this new experiment id?

this is not editable once the feature is created. and we use a different experiment id in our existing event system.

Oh I see. but will this affected what we got on the client side?
