I'm having the same error I wrote them and they said it's takes time for it to cache before ads can be displayed . It been 3 days now and I'm still waiting for the ads to cache. Smart developers they have there at unity.

The error you are seeing usually occurs when a placement has not been loaded and has been requested to be shown anyway.

What you are likely experiencing is a result of recent changes to how the Unity Ads SDK handles the initial loading of placements. As a result of these changes, you are now required to load all placements before showing them. Previously the Unity Ads SDK would request all placements upon initialization, this is no longer the case.

As such you will now need to load your placements. To do this I would advise calling your load function in the Initialization Complete callback.

Now the ad is running, but only the first time, the second time the ad is not running, but gives an error
“Error showing Ad Unit rewardedVideo: NOT_READY - Placement not ready”

public void InitializeAds()
    {
        _gameId = (Application.platform == RuntimePlatform.IPhonePlayer)
            ? _iOSGameId
            : _androidGameId;

        Advertisement.Initialize(_gameId, false, this);
    }

    public void OnInitializationComplete()
    {
        Advertisement.Load(placementId);//
        Debug.Log("Unity Ads initialization complete.");       //
    }

Note: if I place in code “Advertisement.Load(placementId, this);” ,

Error appear “Assets\Resources\PluginNetwork\UnityAds\AdsInitializer.cs(82,41): error CS1503: Argument 2: cannot convert from 'AdsInitializer' to 'UnityEngine.Advertisements.IUnityAdsLoadListener'”

You need to ensure that you are always loading an ad prior to calling the ad to show. The easiest way to do this is to add a load call into your Show Complete callback.

Maybe helpfull for anybody. It's solved

If you just put "Advertisement.Load(placementId, this);" inside a function "OnUnityAdsShowComplete" callback (file RewardedAds.cs), it won't work.

private string _adUnitId = "rewardedVideo";

public void OnUnityAdsShowComplete(string adUnitId, UnityAdsShowCompletionState showCompletionState)
    { 
        Debug.Log(adUnitId);
        if (adUnitId.Equals(_adUnitId) && showCompletionState.Equals(UnityAdsShowCompletionState.COMPLETED))
        {    
            // Grant a reward.
       Advertisement.Load(_adUnitId, this);
}
}

For advertising to work as it should, additionally you need to put "Advertisement.Load(placementId);" inside the function "OnInitializationComplete()" callback (file: AdsInitializer.cs)

    private string placementId = "rewardedVideo";
    public void OnInitializationComplete()
        {
             Advertisement.Load(placementId);//
            Debug.Log("Unity Ads initialization complete.");       //
        }

thanks! it works! after putting “Advertisement.Load(placementId);” inside the function “OnInitializationComplete()” callback…

however, subsequent advertisement invocation shows placement not ready, do I have to always call Advertisement.Load(placementId) before calling Advertisement.Show(“rewarded_video”, this); ? i think we need to do that
