Why are test ads shown instead of regular ones?

Question

Google AdMob

Greetings, for the second day I have been trying to figure out why test videos are shown, here is the code that comes when the application starts:

MobileAds.Initialize(appID);
        this.rewardBasedVideo = RewardBasedVideoAd.Instance;
        AdRequest request = new AdRequest.Builder().Build();
        this.rewardBasedVideo.OnAdRewarded += OnAdRewardedVideo;
        this.rewardBasedVideo.OnAdFailedToLoad += OnAdLoadFailedVideo;
        this.rewardBasedVideo.OnAdLoaded += OnAdLoadedVideo;
        this.rewardBasedVideo.OnAdClosed += OnAdClosedVideo;
        this.rewardBasedVideo.LoadAd(request, GetMoneyVideo);

Here is the code attached to the actions:

void OnAdLoadedVideo(object sender, System.EventArgs args)
    {
        //тут делаю кнопку нажатия активной
    }

    void OnAdLoadFailedVideo(object sender, System.EventArgs args)
    {
        AdRequest _request = new AdRequest.Builder().Build();
        rewardBasedVideo.LoadAd(_request, GetMoneyVideo);
    }

    void OnAdClosedVideo(object sender, System.EventArgs args)
    {
        AdRequest _request = new AdRequest.Builder().Build();
        rewardBasedVideo.LoadAd(_request, GetMoneyVideo);
    }

    public void OnAdRewardedVideo(object sender, System.EventArgs args)
    {
        //тут вознаграждаю
    }

appID and GetMoneyVideo are identifiers from GoogleAdMob and everything created there.
So the problem is that only test videos are shown, not test interstitial ads, and the banner is not shown at all, the banner's OnAdFailedToLoad function is called all the time.
How to fix it?
The logs give this:

I looked with the banner and thought that maybe because of the permission it won’t let me in, I’ll try to download the test device from the play market now, but why is the test device added there?
When downloading from the playmarket, nothing is happening either, the same situation, test advertising + banner is not shown.
I checked the same identifiers on another application and everything works, what is wrong with the applications or the code?
