update Google Mobile Ads-SDK to 20.4.0 needed

[uwe-neuronation]

From what I see on Google Mobile Ads-SDK documentation an update to at least version 20.4.0 would be needed.

Update your app for advertising ID permissions
Apps updating their target API level to 31 (Android 12) will need to declare a Google Play services normal permission in the Android manifest file in order to use the advertising ID. For apps that do not declare this permission and target Android 12, the advertising ID will automatically be removed and replaced with a string of zeros.
You can update your app to GMA SDK 20.4.0+ , which will automatically have the permission declared. If you’re using GMA SDK 20.4.0+ , no further action is required to continue using the advertising ID.
To learn more about the new permission, including how to disable it, refer to the Play Console Help Center.

current nuget is 120.3.0.3 (20.3.0) https://www.nuget.org/packages/Xamarin.GooglePlayServices.Ads/

Deadline is close 1st of April:
Starting in late 2021, when a user opts out of interest-based advertising or ads personalization, the advertising identifier will not be available. You will receive a string of zeros in place of the identifier. This update will expand to all apps running on Android phones, Tablets, and Android TV that support Google Play on April 1, 2022.

What's the plan? Will there be a release soon. It's only two weeks left. Possible workarounds?
Please help!

we can use my libraries :

 <PackageReference Include="Anjo.Android.GoogleServices.Ads" Version="22.0.0" />
 <PackageReference Include="Anjo.Android.GoogleServices.AdsBase" Version="22.0.0" />
 <PackageReference Include="Anjo.Android.GoogleServices.AdsLite" Version="22.0.0" />

Supports fixing the problem of Loading ads using :

• Let's rename for Interstitial ads InterstitialAdLoadCallback to AnjoInterstitialLoadCallback.
• Let's rename for Rewarded ads RewardedAdLoadCallback to AnjoRewardedLoadCallback.
• Let's rename for App Open Ads AppOpenAd.AppOpenAdLoadCallback to AnjoAppOpenLoadCallback.
• Let's rename for Rewarded interstitial ads RewardedInterstitialAdLoadCallback to AnjoRewardedInterstitialLoadCallback.
