Using the “Launched the App” along with the 1st time ever filter on the Insights report (or even cohorts) gives us two sets of users:
- Fresh Installers: Users who have indeed installed and opened the app for the 1st time ever on that particular device
- Re-Installers: Users who had installed the app, uninstalled it due to some reason, and after a hiatus, re-installed it again
Our objective is to segregate these 2 types of users as they would typically exhibit different behaviors (as one set of users have interacted with the app) and sign-up/login tracking would be different (identities on Mixpanel differ pre and post sign-up).
One brute force solution is to get the advertising IDs (GAIDs) of the active users from say Aug-Oct and then map them against the GAIDs for the news users in Nov to get the intersection (re-installers cohort).
Is there any other way in which we can do this? We are not sure if our solution will work and scale as per our expectations.
