Unable to restore user session or receive push notifications when the app is completely closed.

[ManuelMouta]

Description:

We are experiencing a critical issue with Salesforce Mobile SDK version compatibility that affects push notification functionality.

Current Setup:

Marketing Cloud SDK: 9.0.+ (Push notifications)
Salesforce Mobile SDK: MobileSync:13.0.0 (IAM/Authentication)
Firebase Messaging: 23.3.0 (FCM integration)
SFMC Flutter Plugin: ^9.0.0 (Marketing Cloud Flutter wrapper)

Problem:

We seem have a version conflict between Salesforce Mobile SDK versions:
MobileSync 13.0.0:
✅ Push notifications work when app is closed
❌ Some Android devices fail to decrypt local saved sessions
❌ IAM authentication issues on certain devices
MobileSync 13.1.0:
✅ Fixes local session decryption issues
✅ IAM authentication works properly
❌ Push notifications stop working when app is fully closed
❌ SFMCSdk.requestSdk does not respond in background
Code Affected:

override fun onMessageReceived(message: RemoteMessage) {
val customKeys = message.data
val navigationPath = customKeys["navigation_path"] ?:
customKeys["path"] ?:
customKeys["deeplink"] ?:
customKeys["route"]

if (navigationPath != null) {
    // Create intent to launch MainActivity with navigation path
    val intent = Intent(this, MainActivity::class.java).apply {
        flags = Intent.FLAG_ACTIVITY_NEW_TASK or
                Intent.FLAG_ACTIVITY_CLEAR_TOP or
                Intent.FLAG_ACTIVITY_SINGLE_TOP
        putExtra("navigation_path", navigationPath)
    }
    startActivity(intent)
}

if (PushMessageManager.isMarketingCloudPush(message)) {
    SFMCSdk.requestSdk { sdk ->  // ← This fails with 13.1.0 when app is closed
        sdk.mp {
            it.pushMessageManager.handleMessage(message)
        }
    }
}

}

Expected Behavior:
Push notifications should work when app is closed with MobileSync 13.1.0
SFMCSdk.requestSdk should respond properly in background
Local session decryption should work on all Android devices

Actual Behavior:
With MobileSync 13.1.0: Push notifications work when app is open/backgrounded, but fail when app is completely closed
With MobileSync 13.0.0: Push notifications work when app is closed, but local session decryption fails on some devices

Environment:
Android SDK: 34
Min SDK: 28
Target SDK: 34
Kotlin: 1.9.10
Gradle: 8.4
Marketing Cloud SDK: 9.0.+
Firebase Messaging: 23.3.0

Could you please help us find a solution?

@ManuelMouta, I took a detailed look at your issue. I'm not aware of anything in the 13.x releases of Salesforce Mobile SDK which would cause the issue you're seeing. Since you're using the MobilePush SDK for notifications, which I believe is separate from Mobile SDK's notification logic, this issue might be best answered on the MobilePush SDK Stack Exchange. The tag mobilepush-android looks like the one to use. I found that reading at the MobilePush SDK github.io.

It's interesting that you're seeing the issue when changing versions of Mobile SDK. If there's a conflict of some kind between the two SDKs, MobilePush SDK will be best suited to find it for both of us.
