@tanaynigam @jkasten2 any update on this, do you need any more information on this?

I have the same problem, when the app is in closed state, "OneSignal.Default.NotificationOpened += _notificationOpened;" stops working, but if the app is in the foreground or background it works correctly.

Is there any way to fix this?

@tanaynigam @jkasten2 any news on this? Do you have any idea what could be causing this to happen?

I am also having this issue. I would like to deep link from the closed state on android, but this problem is blocking me. Works on iOS

Same issue here (OneSignalSDK.Xamarin 4.1.3 & Android Target 13.0). Any news on this?

Same issue here but with OneSignalSDK.Xamarin 4.3.0 and iOS. On Android everything works great.

Finally found a solution for this problem (Android 13).
I had to put the NotificationOpened handler before the OneSignal initialization. The handler probably worked when the app was in background because then the handler was set (as opposed to a cold start).

OneSignal.Default.NotificationOpened += HandleNotificationOpened;
OneSignal.Default.Initialize(YourOneSignalKey);

I was able to reproduce the issue that you have been experiencing @Dipannita20. I have tested @fatderda's solution and it works.
If your NotificationOpened handler is not firing on cold start put the NotificationOpened handler before the OneSignal initialization.

OneSignal.Default.NotificationOpened += HandleNotificationOpened;
OneSignal.Default.Initialize(<OneSignalAppId>);
