I’ve integrated the https://github.com/fechanique/cordova-plugin-fcm plugin for receiving push notifications.
All seems to work good when the app is in foreground/background but no notification comes when the app is killed.
I’ve opened this issue https://github.com/fechanique/cordova-plugin-fcm/issues/371 discovering that also other guys have the same problem.
I’ve tested on my oneplus 3 and the behaviour is as described.
Notifications arrives also when app is killed on Huawei P8 lite 2017.
The questions are: is this a common issue?
Have you got push notifications also on killed app?
Are you using some other plugins?
