AdMob Interstitial Not Showing into my app


I’m following This tutorial to display interstitial ads.
This is my launchInterstitial() function to display the interstitial ad.

launchInterstitial() {
        let interstitialConfig: AdMobFreeInterstitialConfig = {
            isTesting: true, // Remove in production
            autoShow: true,
             id: "ca-app-pub-xxxxxx/xxx" // ad unit id
        this.admob.interstitial.prepare().then(() => {
            // success

Nothing is showing up.
How do I debug this ?

If you set autoshow to true it should be enough just to call prepare function. Without the then to handle the Promise. That works for me.

can you share your code with me ?

mine is also not working :frowning:
