Why is the unity ad shown and not another one?

Question

Unity

Only the unity ad is always displayed in place of the desired ad.
I set everything up as it should, the ad in my code looks like this (after the end of the level)

public void ShowAds(){
  if(Advertisement.IsReady("UnityAdvAfterEndLevel")){
     Advertisement.Show("UnityAdvAfterEndLevel");
     }
  }

here's what I actually read in the unity panel


on the net that such problems can be if the Store ID is not specified in the unity Dashboard, but I indicated it and it was accepted, by the way, it didn’t accept it before publication, now it’s normally accepted ...
But at the place of advertising , that is, when I went through and the method of showing ads is triggered, the ad of the unit itself is shown ....

What's wrong?

Answer 1

Test mode turned off? In the same place, in the Unity Dashboard
Check if your device is listed as a test device in the Unity Dashboard

Here is from the Unity forum:

I forgot to uncheck the "Ad Test Mode". I've deployed a game onto the google play store and then I've unchecked the check box of "Ad Test Mode". My unity developer said this check box connected to their server so don't worry ad will start working after 1 or 2 days.

If you forgot to uncheck the box before assembly - switch it, in a couple of days the advertisement should start working.
