Hi @Megha1, > I checked the version, found the latest version updated in code. Can you please confirm the version number currently deployed in your app? The version number mentioned in your initial post is not the latest version of the SDK. > We are also not able to reproduce this crash but our users are facing this Can you please try to see if you can reproduce this? Without steps to reproduce it can be very difficult to diagnose the exact cause based on a stack trace and no other information. If you can’t reproduce, any relevant information to the crash would be appreciated so that we can begin investigating. πŸ™‚ Thanks! ---

Hi @Megha1, If you are unsure of which version you are using in your application, this can be checked at runtime by calling [`getVersion`](https://marketplacefront.zoom.us/sdk/meeting/android/us/zoom/sdk/ZoomSDK.html#getVersion-android.content.Context-) through the SDK. πŸ™‚ Thanks! ---
