Hi there, I have a few questions: 1. When visitors first visit a website, they get a primary ID, but after they pass registration, Mixpanel assigns a unique ID to them. What can I do if we need to track users from the point they came to the website and further when they pass registration? How can I match them if, before and after registration, they have different identifiers? 2. Does the retention metric work by default, or do we need to set a specific event, like "User joined," to build a report and see whether a cohort of users came back? Or does it work by default, and we are able to track registered and unregistered users retention? Or it is possible to make a report based on device_id?
