title: Migrated to new SwiftUI App protocol and my FCM notifications stopped working
body: <p>I migrated my app to use the new SwiftUI App protocol and get away with UIKit lifecycle.</p>
  <p>Has anyone managed to get Firebase Cloud Messaging notifications to work with the new #SwiftUI app lifecycle? Get registration token but don't receive any messages. All we are doing is switching <code>@main</code> to our new App view, and using the app delegate adapter.</p>
