Test Ads not displaying

[Unevenn]

Hi I will integrate my app with ironsource sdk but i have problems.
These are given errors
Rewarded Ad: Rewarded Video is not initiated with manual load
Intersitial Ad: No interstitial configurations found

My Android manifest
<activity android:name="com.ironsource.sdk.controller.ControllerActivity" android:configChanges="orientation|screenSize" android:hardwareAccelerated="true" /> <activity android:name="com.ironsource.sdk.controller.InterstitialActivity" android:configChanges="orientation|screenSize" android:hardwareAccelerated="true" android:theme="@android:style/Theme.Translucent" /> <activity android:name="com.ironsource.sdk.controller.OpenUrlActivity" android:configChanges="orientation|screenSize" android:hardwareAccelerated="true" android:theme="@android:style/Theme.Translucent" />

I added activities. and other implementations like

implementation 'com.google.android.gms:play-services-ads-identifier:18.0.1'
implementation 'com.google.android.gms:play-services-basement:18.0.0'
implementation 'com.google.android.gms:play-services-appset:16.0.2'
implementation 'com.ironsource.sdk:mediationsdk:7.2.1'

and in main initialized the ironsource

IronSource.init(appKey: '=======', adUnits: [
  IronSourceAdUnit.Interstitial,
  IronSourceAdUnit.Banner,
  IronSourceAdUnit.RewardedVideo
]);
var userId = await IronSource.getAdvertiserId();
IronSource.setAdaptersDebug(true);
await IronSource.validateIntegration();
await IronSource.setUserId(userId);`

I added the advertiser id of my emulator and real device to ironSource console.
And the issue has not been solved
Any helps please
