Can't call an unskippeable video

Hello, I have an advertisment with the name "rewardedVideo"

For some reason the video shown is still the skippeable one, I believe that I'm calling up the video in the correct method(there isn't too many documentation on the subject)

Could someone give a look to my code and tell me if I missed something important? Thanks!!

 if (Advertisement.IsReady("rewardedVideo"))
         {
             bool resultBool = false;
             hasWatchedVideo = false;
             Advertisement.Show(null, new ShowOptions
             {
                 resultCallback = result =>
                 {
                     switch (result)
                     {
                         case (ShowResult.Finished):
                             resultBool = true;
                             hasWatchedVideo = true;
                             DataManager.instance.VideoReward();
                             break;
                         case (ShowResult.Failed):
                             resultBool = false;
                             hasWatchedVideo = false;
                             break;
                         case (ShowResult.Skipped):
                             //DataManager.instance.VideoReward();
                             resultBool = false;
                             hasWatchedVideo = false;
                             break;
                     }
                 }
             });
             return resultBool;
         }
         return false;
