Answer 1

Hello,

It is caused by the incompatibility of the NuGet Package with Android 12.

You could find the following tips by referring to the NuGet Package Page Microsoft.AppCenter.Push:

This package has been deprecated as it is legacy and is no longer maintained.
Suggested Alternatives
Microsoft.Azure.NotificationHubs

If you don't know how to use Microsoft.Azure.NotificationHubs, please refer to this official guide Azure Notification Hubs for Xamarin.

Best Regards,

Alec Liu.
