Hello, I have a data integrity issue where pre-signup events are not correctly linking to user profiles, impacting our Funnels. Specifically, our dashboard shows users completing sign-up without a preceding view_firstscreen event, though we can see the view_firstscreen event in their raw activity feed. 1. The Problem & Our Observations
This discrepancy began after a recent Code Push update to our app. We’ve noticed a key pattern for users with incorrect data: their view_firstscreen event includes a Preshuffle Distinct Id property in the Your Properties section (see attached image). This is unusual as it’s a Mixpanel internal property.
Conversely, for users with correct data, the Distinct ID Before Identity property appears as expected in the Mixpanel Properties section.
2. Our Questions
Why is Preshuffle Distinct Id being recorded in our Your Properties section?
What is the difference between Preshuffle Distinct Id and Distinct ID Before Identity?
We suspect our Code Push update may be causing the SDK to improperly manage the anonymous ID, preventing the identify call from correctly linking pre-login events. What steps should we take to debug and resolve this issue?
