Any update on this? In Android, if the app is in the background, the notification appears but does not display any sort of heads up display/banner and stays in the notification drawer. So there is no visual way of telling the user that the notification has arrived. Works fine on iOS though. Maybe there's a setting that I'm missing?
Running: Android Lollipop MiUi ROM (but same results on a Nexus 6 as well)
