why are some page load events in Mixpanel not linked to the distinct ID of the user despite the user has logged in for authentication purpose. How to resolve this issue? Is this a client side problem and how to communicate this to a client

This issue is likely related to identity management in Mixpanel. There are a few potential reasons why page load events might not be linked to the correct distinct ID after user authentication: 1. Delayed ID merge: According to the Identifying Users (Original) FAQ, it can take up to 24 hours for ID mappings to propagate through the system. This means that some events may appear unlinked in real-time analysis, even though the user has logged in.2. Incorrect implementation of identify() call: The client may not be calling the identify() method correctly after user authentication. This is crucial for linking pre-login and post-login events.3. Reset() being called unnecessarily: If reset() is called too frequently, it can create new device IDs and break the user identity chain.To resolve this issue: 1. Ensure proper implementation: The client should call identify() upon login or when the app is reopened in a logged-in state. This is mentioned in the Best Practices section.2. Check for correct ID usage: Make sure the client is using the correct user ID when calling identify(). A common mistake is using a static string instead of the actual user ID, as mentioned in the Hot Shard Limits documentation.3. Review reset() usage: Ensure reset() is only called when there's an explicit intent to change to a new user, such as clicking a "Sign-up" button.4. Implement super properties: Track the user's unique identifier as a super property to assist in troubleshooting.This is indeed a client-side problem. To communicate this to the client: 1. Explain the importance of proper identity management in Mixpanel. 2. Provide them with the Best Practices documentation for implementing identity management. 3. Suggest a review of their current implementation, focusing on the identify() and reset() calls. 4. Recommend QA testing during the development phase to ensure events are correctly linked across the user journey. 5. Advise patience, as some delay in ID merging is normal and can take up to 24 hours.By following these steps, the client should be able to resolve the issue and ensure that page load events are correctly linked to authenticated users.
