[Solved]Unity ads not showing

I just activated the Unity ads function and created an empty game object to manage the ads and added it a script called "AdManager", which simply contains the contents of the sample code for rewarded ads (yes, I did change the class name to match the script name). I proceeded to create a button, and assign it the empty game object and make it call the ShowRewardedAd() method but whenever I click it, it doesn't load the test ads. I know that it's being called, because I tried adding an 'else'...
