Bug Unity Ads 3.7.5 and 4.1.0 LoadListener always call the OnUnityAdsFailedToLoad

I used the Unity Ads developer integration guide.

After "Advertisement.Load("Android_Interstitial",this);" the Unity Ads SDK always call only the OnUnityAdsFailedToLoad() event with Timed_out error.

The ads are loaded, the "Advertisement.Show("Android_Interstitial");" shows the ads.

With Unity Ads 3.7.5 I can check the loaded ads with Advertisement.IsReady(),
but in Unity Ads 4.1.0 does not contain Advertisement.IsReady().

Please put Advertisement.IsReady() back in the Unity Ads 4.1.0 and above.
Advertisement.IsReady() works fine.

Another problem found. There is no close (X) button on interstitial ads.

 

Hi xGeorgeV, the close button is a BIG problem, every Unity Ads user should take a look on this post:https://forum.unity.com/threads/be-careful-to-use-unity-ads-4-1-0.1279820/

 

Same problem with Unity Ads 4.2.1 (with Unity 2020.3.35f1).

Advertisement.Initialize( sUnityAdsAndroidGameID, false, this );
Advertisement.Load( "Android_Interstitial", this );

OnUnityAdsFailedToLoad:
I/Unity: Error loading Ad Unit: Android_Interstitial - TIMEOUT - [UnityAds] Timeout while loading Android_Interstitial

PLEASE PUT BACK Advertisement.IsReady() IN THE Unity Ads 4.2.1 AND ABOVE!
Advertisement.IsReady() WORKS FINE! (With Unity Ads 3.7.5)

 

Unity Ads 4.2.1 with Unity 2020.3.35f1.

Advertisement.Load( "Android_Interstitial", this );
Load the advertisment but always returns the OnUnityAdsFailedToLoad event:
I/Unity: Error loading Ad Unit: Android_Interstitial - TIMEOUT - [UnityAds] Timeout while loading Android_Interstitial

Advertisement.Show( "Android_Interstitial", this );
Show the advertisement but always returns the OnUnityAdsShowFailure event:
Error showing Ad Unit Android_Interstitial: INTERNAL_ERROR - [UnityAds] Timeout while trying to show Android_Interstitial

From logcat:
:: Initializing Unity Services 4.2.1 (4210)
:: Unity Services environment check OK
:: Unity Ads init: load configuration
:: Received configuration for token
:: Unity Ads event: sending start event
:: Closing Unity Ads ad unit

Something goes wrong...

This interface style eventhandler (callback) is a bad idea for ads, because in this case the advertisment class cannot be static.
For example: "public static class UnityAdsAndroid".

Advertisements are used in many different parts of the program, therefore it is better way to have a static advertisement class.

The better way is to use the Advertisement.isReady() ( Advertisement.isInterstitialReady(), Advertisement.isRewardedReady(), ... ) instead of callbacks. Easy to use, fast integration, more stable operation, faster update, satisfied developers...

 

Just find this line in the log above...

2022-06-15 11:32:47.054 11397-11430/? I/Unity: Error loading Ad Unit: Android_Interstitial - TIMEOUT - [UnityAds] Timeout while loading Android_Interstitial

 

Same problem with Unity Ads 3.7.5. TIMEOUT.

 

Event timing is unusable.

ShowStart Event after Closing Unity Ads:
