Right now I am just trying to show an Ad On click of a button… It is because, I wanted to know if the Ads are working…
import UnityEngine.Advertisements;
function Start(){
}
function Update() {
}
function ShowAd(){
Advertisement.Show();
}
ShowAd() is applied to onclick for a button
Right now all I want to do is show an adertisement on the click of a button…
So i have enabled unity ads, enabled enabled test ode, enabled built in extensions and no errors too…
So if i play the game in editor, I will get the screen which says “Your Ad will be here, Everything seems to be working” right ? Please reply soon… 
Rgiht now hen I click the button nothing happens
