I read your comment in another post, in which you told to use 6.0.312 vut could not use the exact version, if this is the case then how can I integrate 6.0.312 in project.

Regards,
mauiprogram.cs

    private static MauiAppBuilder RegisterFirebaseServices(this MauiAppBuilder builder)
    {
        builder.ConfigureLifecycleEvents(events => {
#if IOS
            events.AddiOS(iOS => iOS.FinishedLaunching((app, launchOptions) => {
                CrossFirebase.Initialize(CreateCrossFirebaseSettings());
                CrossFirebaseCrashlytics.Current.SetCrashlyticsCollectionEnabled(true);
                return false;
            }));
#else
            events.AddAndroid(android => android.OnCreate((activity, _) =>
                CrossFirebase.Initialize(activity, CreateCrossFirebaseSettings())));
                CrossFirebaseCrashlytics.Current.SetCrashlyticsCollectionEnabled(true);
            CrossFirebaseCloudMessaging.Current.NotificationTapped += (sender, e) =>
            {
                System.Diagnostics.Debug.WriteLine("tabbed");
                Shell.Current.GoToAsync(nameof(Specspage));
            };
#endif
        });

        builder.Services.AddSingleton(_ => CrossFirebaseAuth.Current);
        return builder;
    }

Please note that you implemented the NotificationTapped only on Android, so it will not work on iOS.

Also, this code is not enough to determine if you are initializing the Plugin.Firebase correctly.

Here is a sample, with Plugin.Firebase + .NET7 + MAUI that works fine on iOS, please check the complete plugin initialization.

Also, on the Tapped event, check if if you have a valid instance:

if (CrossFirebaseCloudMessaging.Current != null)

And if you have a valid notification:

if (e != null && e.Notification != null && e.Notification.Data != null)
