Admob ads not showing (gray bar), and the test it works


I want to add admob ads to my app and i installed the admob-free
I import it in app.component.ts inside this.platform.ready() and when i remove property id the test ads work, and when i put my id banner… banner not works just the gray bar appears !!!

PS: I created the ads banner and i wait over 10hours, but not work

this is my code :

initializeApp() {
this.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.

  const bannerConfig: AdMobFreeBannerConfig = {
    id: 'ca-app-pub-8170715615132481/1381589343',
    isTesting: false,
    autoShow: true
  this.admobFree.banner.prepare().then(() => {;
  }).catch(e => console.log(e));

When i remove id and i put isTesting=true

When i put id and i put isTesting=false
