Can't dismiss Admob Interstitial Ads by pressing Back key button of Android device

问题

I am using latest Ads library ('com.google.android.gms:play-services-ads:19.3.0')

Recently, It is unable to close an Interstitial ads by pressing Back key button. I have to tap on "Close" button from Ads UI to dismiss the Ads.

Any body had same problem? Is it a new feature of Admob?

  MobileAds.initialize(this);
interstitialAd = new InterstitialAd(this);
interstitialAd.setAdUnitId("ca-app-pub-3940256099942544/1033173712");
interstitialAd.loadAd(new AdRequest.Builder().build());
tvTitle.setOnClickListener(v -> {
if (interstitialAd.isLoaded()) {
interstitialAd.show();
}
});

I've this too. I've talked with people at AdMob and asked if they changed the behavior of their ads and they confirmed that they did. It's no longer possible to use the "Back" button to dismiss the interstitial ad and they told me that no changes are required on my side. I guess users must use the "Close" or "X" button within the ad itself to close it.
