Possibly related to this issue?: https://github.com/googleads/googleads-mobile-unity/issues/976#issuecomment-558753013 That is, AdMob events don't necessarily call back to the handlers using the Main Unity thread.

Hi, I have the same issue. Did you managed this problem somehow?

Hi, I have the same issue. Did you managed this problem somehow?

We happen to be using UniRx, so we used their MainThreadDispatcher method in the event handler hookup, like this: _rewardedAd.OnUserEarnedReward += (object sender, Reward e) => MainThreadDispatcher.Post(_ => RewardedVideoAdRewardedEvent(sender, e), null);
