I tried the sample code from sample project in , basically followed the same steps as below:
AdRequest ad = new AdRequest.Builder().AddKeyword("unity-admob-sample").Build();
string adUnitId = "unused"; (since I demo on Editor)
rewardedAd = new RewardedAd(adUnitId);
rewardedAd.LoadAd(ad);
However, the debug log window popped up "No prefab found" after rewardedAd.LoadAd(ad); then the "video ad failed to show, because no ad loaded". What's the possible reason causes the load video behavior fail on my project? Because I could run the sample project successfully, Is it due to I didn't upgrade my admob plugin to latest version?
Thank you.
