Ionic Back button fails when Admob ad shows

I managed to show the Admob test Banner in the bottom of one of my views but now the navigation back button to the root view through the top navbar fails.

Is the ADmob logic somehow overriding the ui interaction?
Is this because as of now I am showing the test ad only?
My implmentation is based on the default example

Code below:

import * as moment from 'moment';

import { AdMobFree, AdMobFreeBannerConfig } from '@ionic-native/admob-free';

import { SocialSharing } from '@ionic-native/social-sharing';
import { Component, ViewChild } from '@angular/core';
import { IonicPage, NavController, NavParams, LoadingController, Platform, Slides } from 'ionic-angular';


const bannerConfig: AdMobFreeBannerConfig = {
  // add your config here
  // for the sake of this example we will just use the test config
  isTesting: true,
  autoShow: true
  selector: 'page-forecast',
  templateUrl: 'mypage.html',
  providers: [AdMobFree]
export class ForecastPage {

  constructor(public navCtrl: NavController, 
              public navParams: NavParams,
              private _admobFree: AdMobFree) {


    .then(() => {
      console.log('\nSHOWING BANNER!\n');
      // banner Ad is ready
      // if we set autoShow to false, then we will need to call the show method here
    .catch(e => console.log(e));

  ionViewDidLoad() {
    console.log('Hello World')
