Unable to Override distinct_id in Mixpanel After Calling identify

[sharifelshalabi]

I am encountering an issue with setting a custom distinct_id for Mixpanel events. Currently, Mixpanel defaults to using the device ID as the distinct_id. I am attempting to override this by explicitly calling identify with a custom user ID. My code is structured as follows:

instance
   .identify(user.id?.toString() ?? '')
   .then((_) => user.analyticParams.forEach(instance.getPeople().set));

The expected behavior is that Mixpanel should use the user.id provided in the identify method as the distinct_id for all subsequent events. However, it seems that Mixpanel still defaults to the device ID instead of the custom ID I've set.
