Issues with First Session Detection Using Special Parameters

·
·

With some users, we can see that the first sessions of the day are not detected with the special parameters. Then it starts to work great. Any thoughts?

    Based on the information provided in the knowledge sources, there could be a few reasons why the first sessions of the day are not detected with special parameters for some users. Here are some thoughts on potential causes:1. Session Reset: Mixpanel resets sessions every 24 hours at midnight according to your project timezone. As mentioned in the Sessions documentation, "Sessions are reset every 24 hours at midnight (according to your project timezone), so the maximum session length is 24 hours." This reset could potentially affect the detection of the first session of the day.2. Event Skipping: There might be an issue with event tracking for the first session. As described in the Product analytics implementation hiccups blog post, events can sometimes be skipped in non-obvious circumstances. This could be due to specific tracking logic implemented by engineers.3. Delayed Data Processing: There might be a delay in processing the data. According to the Funnels FAQ, "there may be up to a 24 hour delay on our reports (except for Activity Feed), as we work towards linking anonymous user activity to known profiles."4. Implementation Issues: There could be issues with how the session tracking is implemented. It's worth reviewing the implementation, especially if you're using custom session tracking methods.To troubleshoot this issue, you could:1. Check your session configuration in Project Settings to ensure it aligns with your expectations. 2. Review your implementation, particularly for the first events of the day. 3. Use debug mode to confirm that requests are being sent to Mixpanel correctly for these first sessions. The Debugging documentation provides instructions on how to enable debug mode for various SDKs.If the issue persists after these checks, it would be advisable to contact Mixpanel support for more detailed troubleshooting, as the knowledge sources don't provide enough information to definitively solve this specific problem.
