Issue with UnityLevelPlay(IronSource SDK) and API 33

I did a previous post where I had an issue installing the plugin to migrate from Unity Mediation seen here: Issues with IronSource SDK after successfully integrating the plugin, now Google is requiring all apps to meet API Level 33 till 31/8.
Now I have an issue when running my android application
I’m getting the following error:
AndroidJavaException: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/ironsource/mediationsdk/sdk/InitializationListener; At the initialization part of the code. IronSource.Agent.init(id);

I tried to move the android-bridge.jar to Assets/IronSource/Plugins/Android but had no success

Thanks for your question. please make sure you upgraded LevelPlay SDK/plug-in to the latest version:

and make sure you implemented the correct methods and delegates. If the issue persists, please goto your LevelPlay account → upper right corner → Contact Us

Thank you I did update it form the link provided, I have another issue, using the sample scene, I have changed the game key and when I press Load Interstitial I get error: code: 508, description : Interstitial - the server response does not contain interstitial data. Why does this happen?

it’s more AppKey configuration relevant, since the AppKey is pretty credential, I recommend you to raise a case here to our support team with all the details.
