Retention report. I'm trying to show a breakdown by property of first event. But 'breakdown' breaks down by property of every event in the funnel. I can kindof achieve this by clicking the "filter" next to the first event and then picking the value of the first event. But then I only get the retention rate for a specific value, not a breakdown of all values

Retention report. I'm trying to show a breakdown of signup rate by 'refer' property. The thing is, I only care about the 'refer' property for the first event. If I use 'breakdown' it says the rate is 0% for every referral source because by the time they sign up refer is mysite.com

Why is mixpanel.people.set(...) not updating an existing profile in mixpanel? If I'm trying to update an existing property, it never fails. But sometimes trying to update an existing profile via people.set() does nothing.

Is there a rate limit to how many user profiles I can update via mixpanel.people.set(...)

Is it possible to send an event and forward date it so that it's dated at some point in the future?
