    Hello there,

    We are building an iOS app using Xamarin Studio. While launching the app from background, it crashes sometimes. We are getting following crash log from device but we are not getting clear idea due to which the crash is happening.

    Aug 6 22:09:51 Ashishs-iPhone SpringBoard[54] : Forcing crash report of (reason: 1, description: com.smarterme.appstoredevelopment failed to scene-update in time) Aug 6 22:09:51 Ashishs-iPhone SpringBoard[54] : Application 'UIKitApplication:com.smarterme.appstoredevelopment[0x4769]' exited abnormally via signal.

    We are not getting the exact reason/issue due to which it is crashing.

    FYI, In our app, we have used following techniques for network calls/to connect to server. 1. async and await 2. Background Worker 3. Background Fetch mechanism provided by iOS.

    Has anyone came across such crash Your valuable inputs will be helpful.

    Thanks in advance.
