Ionic 3 not receiving push in background mode

#1

Ionic does not receive token in the background, only in the foreground
While the application is open in HomePage I get the notification by the alert, but when this application closes I do not get the notification

home.ts

setTokenPush(){
    const options: PushOptions = {
      android: {
      },
      ios: {
        alert: 'true',
        badge: true,
        sound: 'true'
      },
      windows: {},
      browser: {
        pushServiceURL: 'http://push.api.phonegap.com/v1/push'
      }
    };

    const pushObject: PushObject = this.push.init(options);
    pushObject.on('notification').subscribe((notification: any) => {
    alert(notification.message);
    });
    pushObject.on('registration').subscribe((registration: any) => {
      this.configPushUser(registration.registrationId);

    });

    pushObject.on('error').subscribe(error => {
    });

  }
  configPushUser(token){
    this.webservice.configPushUser(token).subscribe(data=>{
    });
  }

Even sending by firebase cloud message I do not get …

Send Notification backend config(laravel+php)



	$data = array(
				"to" => $user->token_push,
				"notification" => [
					"title" =>'You receive '.$value.' Bitcoin' ,
					"sound" => "default",
					"body" => 'Tap to view',
				],
				"data" => [
					"data" =>[
						"datas" => [
							"ethereum"=>$ethereum,
							"bitcoin"=>$bitcoin,
							"litecoin"=>$litecoin,

				],
			);
			$data = json_encode($data);
			$curl = curl_init();
			curl_setopt_array($curl, array(

try this

$data = array(
				"to" => $user->token_push,
				"data" => [
                                     "title" => 'You receive '.$value.' Bitcoin' ,
                                     "body" => "Tap to view",
                                     "notId" => 1,//Uniqe id for any notification,
                                     "ethereum" => $ethereum,
                                     "bitcoin" => $bitcoin,
                                     "litecoin" => $litecoin
				],
			);
			$data = json_encode($data);
			$curl = curl_init();
			curl_setopt_array($curl, array(
				CURLOPT_URL => "https://fcm.googleapis.com/fcm/send",
				CURLOPT_RETURNTRANSFER => true,
				CURLOPT_ENCODING => "",
				CURLOPT_MAXREDIRS => 10,
				CURLOPT_TIMEOUT => 30,
				CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
				CURLOPT_CUSTOMREQUEST => "POST",

			$response = curl_exec($curl);
			$err = curl_error($curl);

			curl_close($curl);

More details about the platform (OS, Push plugin) would help.
Is this on Android or iOS?
