We are facing the problem in sending GCM push notifications to all the android devices. We are developing an app on Ionic platform and using the plugin called cordova push for the push notifications. The device is registering with gcm and receiving device token. I am using 3 devices to test Moto g4 plus, MI4 and Letv.
The problem is push notification is reaching to moto g4 plus device but not to MI and Letv devices when the app is killed. MI and Letv devices are also receiving the notification only when the app is in the foreground or background.
I am receiving delivery receipts from gcm as delivered to all the devices in the app killed case too.
Please suggest some solution to overcome this problem. Thank you.
