I wrote a code to call the identify function after the user logs in.
When I tested it, distinct_id was replaced with user_id as I intended.
However, when I look at the mixpanel event list of other users, distinct_id is assigned to device_id at the time identify is called, and user_id is assigned to a property called ‘Distinct ID Before Identity’. Why is there an item called ‘Distinct ID Before Identity’ property, and why is distinct_id not replaced with user_id?
