I would like to understand why some users are updating days late.

Based on the knowledge sources provided, I can explain why some users might be updating days late in Mixpanel. This is a common occurrence and there are several reasons for it: 1. Offline Mobile Clients: If a user's mobile device is offline, the data may not be sent to Mixpanel immediately. As mentioned in the Data Pipelines Overview FAQ, late-arriving data can take up to one day to sync from Mixpanel to your destination.2. Import API: The Import API allows for adding data to previous days, which can result in late updates. This is mentioned in the Schematized Export Pipeline documentation.3. GDPR-related Deletions: Delete requests related to GDPR compliance can cause deletion of events and event properties, which may appear as late updates in your data.It's important to note that Mixpanel has mechanisms in place to handle these late-arriving data points: - Data Sync: Mixpanel can detect changes in your data with the granularity of a day and replaces the old data with the latest version in both object storage and data warehouse (if applicable).- Service Level Agreement: According to the Service Level Agreement, Mixpanel allows for an additional 24 hours for late-arriving data on top of the standard 24-hour end-to-end latency policy for exported events.- Late Data Definition: Mixpanel defines late data as any data point or user profile update that reaches Mixpanel servers later than two hours after the end of the export window.To ensure you're getting the most up-to-date data, it's recommended to enable the sync feature for your data pipelines, which helps keep the data fresh and minimizes missing data points. However, keep in mind that even with sync enabled, it may take more than 2 days for the data in the destination to be fully in sync with the data in Mixpanel.
