Not getting Notification for my door bell

Need help I have all my notifications on. All permission is on. Background apps are set to run all time and I am still not getting Notification when someone walks up to my door if the app is close. I am using a note 10 and it’s having issues but my wife’s iPhone is working properly. Any tips on fixing this issue for Samsung note 10.

I’m having same issue. I’ve followed the instructions to allow notifications but I still don’t receive any notifications. I’m using Samsung S9+
