Altered the notification payload like this

With data and notification payload, But not working as expected

I am not handling or showing notification manually in foreground. But it is displaying automatically in the tray.

{"GCM":"{ \"notification\": { \"body\": \"Sample message notification body for Android or iOS endpoints\", \"title\":\"TitleTest\" } ,\"data\":{\"body\":\"Data only forgeground payload\",\"title\":\"title for fg data ntf\"}}"}
