FlutterApplovinMax.initInterstitialAd don't have a loaded event

[mikron123]

After FlutterApplovinMax.initInterstitialAd a loaded event is not fired.
Even if we use

await FlutterApplovinMax.initInterstitialAd("AD_ID");
bool isInterstitialVideoAvailable = await FlutterApplovinMax.isInterstitialLoaded(listener);

The listener is not triggered, and isInterstitialVideoAvailable is false. After a few seconds if we check again, it's true.

How can we tell if an ad was indeed loaded / failed to load?
