Android – why doesn’t the AdMob advertising frequency limit work?

I set up two display times per minute for each user, but it didn't work. The advertisement will be displayed every time

On the AdMob website, they said: changes to the frequency limit, such as changing the limit from 2 to 3, may take a day to take effect

But more than five days have passed since I applied the change to the frequency limit and it doesn't work properly? Here's how I advertise:

private void requestNewInterstitial() {
        AdRequest adRequest = new   AdRequest.Builder().addTestDevice("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX").build();
        mInterstitialAd.loadAd(adRequest);
}

I use settestdevice, so the real advertisement will not display the application, because the display on the real advertisement may prohibit me

resolvent:

AdMob only sets the frequency limit for real ads, not test ads. try to delete your test equipment and observe real ads. the frequency limit works. I have tried and tested it on emulator and real devices. I can't find the documents for reference. This is my experience

As for –

>When not added as test equipment, the upper frequency limit is valid > the upper frequency limit cannot be added as test equipment

Hope to help you:)
