Duplicate onNotification calls

Hey,

I appear to be getting duplicate notifications for both iOS and Android. For a given push (without interaction) I get the onNotification handler called twice. For noisy/mixed notifications this means two notifications are shown in the notification centre.

E.g. from Android This one appears to have the google metadata

{
    color: null
    data: {someData: "example"}
    finish: ƒ finish()
    foreground: true
    google.delivered_priority: "normal"
    google.message_id: "0:1559037885338181%6af40c24f9fd7ecd"
    google.original_priority: "normal"
    google.sent_time: 1559037885334
    google.ttl: 2419200
    id: "1513948521"
    message: "aBody"
    pinpoint.campaign.campaign_activity_id: "ad08775a9d21480aab6768c024060627"
    pinpoint.campaign.campaign_id: "24d11aa26b934153b5bde9205993e33e"
    pinpoint.campaign.treatment_id: "0"
    sound: "default"
    title: "aTitle"
    userInteraction: false
}

This one appears is the same but without google metadata

{
    color: null
    data: {someData: "example"}
    finish: ƒ finish()
    foreground: true
    id: "1505484046"
    message: "aBody"
    pinpoint.campaign.campaign_activity_id: "ad08775a9d21480aab6768c024060627"
    pinpoint.campaign.campaign_id: "24d11aa26b934153b5bde9205993e33e"
    pinpoint.campaign.treatment_id: "0"
    sound: "default"
    title: "aTitle"
    userInteraction: false
}

is anybody else experiencing this?

@SilwalUjjwal Thank you very much. You were bang on the money.

https://developers.google.com/cloud-messaging/android/android-migrate-fcm agrees with you stating

The FCM SDK automatically adds all required permissions as well as the required receiver 
funtionality. Make sure to remove the following obsolete (and potentially harmful, as they 
may cause message duplication) elements from your app's manifest:

I removed

   <!-- < Only if you're using GCM or localNotificationSchedule() > -->
        <receiver
                android:name="com.google.android.gms.gcm.GcmReceiver"
                android:exported="true"
                android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <category android:name="${applicationId}" />
            </intent-filter>
        </receiver>
        <!-- < Only if you're using GCM or localNotificationSchedule() > -->

and no longer receive them twice

Thanks again

@hukpavlo , no, but I updated my implementation to make sure it doesn’t affect the app functionality when user clicks on notification.
