Hi there! I following this tutorial https://learn.unity.com/tutorial/unity-monetization-rewarded-ads# I copy all of that code to my game, my game is iOS game, But when I try to play the Ads not even OnInitializationComplete() to play it just stop at Start()... so my game still no Reward Ads, what did I wrong? or my game need to pass review and released on App Store first! to go further? anyone having this issue? Thanks!
