I am working at Dev Technosys and currently facing a real-time data synchronization issue in one of our mobile applications. The app relies heavily on live data updates—such as user activity, messages, and transaction status—but we’re noticing inconsistencies between the client and server data.


In some cases, the app doesn’t reflect updates instantly, while in others, it shows outdated or duplicated data. This becomes more problematic when multiple users interact with the same data simultaneously, leading to conflicts and mismatched states across devices.


Our architecture includes REST APIs along with some real-time mechanisms like WebSockets and push notifications. However, we suspect that issues like network latency, improper state management, caching conflicts, or missed socket events might be causing the synchronization gaps. Offline mode handling and retry logic might also be contributing to inconsistent data once the connection is restored.


We’ve tried implementing basic solutions like periodic syncing, improving API response handling, and optimizing backend performance, but the problem still occurs under certain conditions, especially with unstable network connections.


Has anyone experienced similar real-time data synchronization issues in mobile app development? What were the root causes in your case, and how did you ensure consistent and reliable data syncing across users and devices? Any recommendations on tools, architecture patterns, or debugging approaches would be really helpful.
