Ionic Native Code Push rollback problem

Hello, im having a problem with de Code Push Plugin. This is the code that im using:

import { Component } from ‘@angular/core’;
import { Platform } from ‘ionic-angular’;
import { StatusBar } from ‘@ionic-native/status-bar’;
import { SplashScreen } from ‘@ionic-native/splash-screen’;

import { HomePage } from ‘…/pages/home/home’;

import { CodePush, InstallMode, SyncStatus } from ‘@ionic-native/code-push’;
import { AlertController } from ‘ionic-angular/components/alert/alert-controller’;

@Component({
templateUrl: ‘app.html’
})
export class MyApp {
rootPage:any = HomePage;

constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen,
private codePush: CodePush, private alertCtrl: AlertController) {
platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
statusBar.styleDefault();
splashScreen.hide();
this.checkCodePush(); //Use the plugin always after platform.ready()
});
}

checkCodePush() {

 this.codePush.sync({
  updateDialog: {
   appendReleaseDescription: true,
   descriptionPrefix: "\n\nChange log:\n"
  },
  installMode: InstallMode.IMMEDIATE

}).subscribe(
(data) => {
alert('CODE PUSH SUCCESSFUL: ’ + data);

 },
 (err) => {
  alert('CODE PUSH ERROR: ' + err);

 }

);
}

}

   The problem is that after the app is updated i close the app, and it rollback to the previus version, but there are no error with the update. Someone can help me with this?

Did you solve this problem?
