Notification: receive ONLY when app is off or background

Hi guys!

I am implementing push notification for the chat in my app.
It is working fine. I am properly receive the notification - sent with a cURL request when a new message is sent.

The thing is:

Back in the days with Ionic 1 - I was receiving the notification only when the app was off or in background.
Now i receive the notification also when the app is on - when I don’t need it.

How can fix this?

The cURL request in the API is exactly the same (just updated the profile and token)

For the code in the app I am following the documentation.

This how I register the user after the login:

this.push.register().then((t: PushToken) => 
{
	return this.push.saveToken(t);
}).then((t: PushToken) => 
{
	// save t.token in database
});

And for the subscribe to the notification I have nothing yet:

this.push.rx.notification()
.subscribe((msg) => {
	// alert(msg.title + ': ' + msg.text);
});

Any suggestion?

Thank you very much!
