Mixpanel not recording events for some users despite account creation on Android and iOS platforms
Hi, We are experiencing an issue with Mixpanel where, for a subset of users, no events are being recorded even though the users have successfully created their accounts and are actively using the app. The issue affects both Android and iOS platforms. For the impacted users, we do not see any events in Mixpanel, including basic events such as first_open and app_open. We have already worked closely with Mixpanel Support and implemented all the recommended troubleshooting steps. We have also thoroughly investigated the following potential causes:
ID Management— Improper identity management (e.g., mismatched anonymous and identified user IDs) can result in events being tracked under unintended profiles or dropped entirely.
Mobile SDK Flush Behavior— Mobile SDKs batch events locally and flush them to Mixpanel on a timer. If the app is force-closed before a flush occurs, any queued events will not be sent and will be lost.
Poor Network Connectivity— On unstable or offline connections, the SDK queues events locally. If the app is terminated before the connection is restored and the queue is flushed, those queued events will be permanently lost.
Despite these checks and fixes, the issue persists for a small group of users, and no events are being received in Mixpanel for them. We would appreciate any additional guidance on potential root causes or further troubleshooting steps.
