I have created a Xamarin.Android application targeting Oreo 8.1. I integrated Firebase notifications in my application. It was working fine till now but since last week I am getting strange error where var token = FirebaseInstanceId.Instance.Token; returns null. Also my FirebaseInstanceIdService does not get invoke when my app is installed for the first time on user's device.
I have tried several solutions including firebaseinstanceidservice-gettoken-returning-null
I tried to clean my solution several times even deleted bin and obj folders but still no use. I even tried to create new Firebase console app's google-services.json file but still receiving the same problem.
I will really appreciate your help. Thanks
