Quickstart-ios: iOS Notification not appearing in the notification tray when app is killed

[mrithula-quintet]

Hi,
I don't receive notifications in my notification tray when the app is killed from the background. Can someone let me know how can I fix this issue?

Thanks,
Mrithula

I am also having similar problem. When i send notification from console its shows in device logs in emulator. But when i am running in testflight it is showing nothing.

I had same issue, setting notification priority to high worked for me

Hi! I have this issue too. Could you help me, please!

Make sure you have enabled "push notification" in xcode capabilities and "remote notification" is added in background mode which is also is xcode capabilities.

@sadh Of course this is implemented. App receives push notifications when it is in background mode. But if I kill the app, it doesn't receive notifications. Also the error appears with title "Failed to fetch APNs token". All certificates loaded to Firebase console.

Same problem (iOS 8, 9, 10).
"Foreground" & "background" modes work as expected, but iOS doesn't even show notifications for "killed"(Home+Swipe Up) app. Another strange behaviour: if you send notifications while app is killed and then run it, sent notifications are delivered sometimes(very rarely, 1/80 chance).
Tried both own server and Firebase console.
Setting "priority" property to "high" resolves the problem, but it's unwelcome solution.

This sounds like its just the behavior of APNs/iOS when apps are receiving lower priority messages in a killed state. Definitely feel free to raise a feature request if there is an alternative approach you'd like FCM to take, but otherwise I'm not sure this is directly addressable: https://firebase.google.com/support/contact/bugs-features/
