Duplicate notifications are triggering when app is in background with FCM

I am getting duplicate notification (FCM) when app is in background , and only getting single notification when app is in foreground or close, but the problem lies with background state

This issue should not occured with the latest version, you will need to check the installation process in the README. Many settings in AndroidManifest are not required anymore.

it looks like removing this fix the duplicate notification:

<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() > -->
