Android foreground service notification not showing (Maybe only in Oreo)

1. What version of RN and react-native-fcm are you running?
I am using expo version 23. RN version will be 0.50.
react-native-fcm version is 11.0.1.
2. What device are you using? (e.g iOS9 emulator, Android 6 device)?
I am using pixel 2 with Oreo.
3. Is your app running in foreground, background or not running?
I am receiving notification well in background with notification icon at the statusbar. However when app is in foreground, icon at statusbar is not showing. However I am receiving FCMEvent.Notification well without notification at statusbar in foreground.
I've tried many things and coudn't solve it. I need your help for this.

I think this link is related to my problem. Can you update your package to support this?
