"PendingIntent must be mutable" error using Geofencing

I have created a .NET MAUI 10 App that uses geofencing to allow users to verify if a location is valid and to add reviews using Actions. When I add .UseLocalNotificationGeofence to MauiProgram.cs, I get the following error: "10: PendingIntent must be mutable". If I remove the line from MauiProgram, i do not get the error. Here is the JavaException:

"com.google.android.gms.common.api.ApiException: 10: PendingIntent must be mutable

I am creating the NotificationRequests based on a collection of Locations that the user has requested. Here is my MauiProgram.cs code:

.UseLocalNotification(config =>
{
config.AddCategory(new NotificationCategory(NotificationCategoryType.Status)
{
ActionList =
[
new(100)
{
Title = "Yes",
Android =
{
LaunchAppWhenTapped = false,
IconName =
{
ResourceName = "launcher_40"
}
},
Apple =
{
Action = Plugin.LocalNotification.Core.Models.AppleOption.AppleActionType.Foreground
}
},
new(101)
{
Title = "No",
Android =
{
LaunchAppWhenTapped = false,
IconName =
{
ResourceName = "launcher_40"
}
},
Apple =
{
Action = Plugin.LocalNotification.Core.Models.AppleOption.AppleActionType.Foreground
}
},
new(102)
{
Title = "Add Review",
Android =
{
IconName = { ResourceName = "add.png" },
LaunchAppWhenTapped = true
},
Apple =
{
Action = Plugin.LocalNotification.Core.Models.AppleOption.AppleActionType.Foreground
}
}
]
})
.AddAndroid(android =>
{
android.AddChannel(new AndroidNotificationChannelRequest
{
Id = "",
Name = "",
Description = "",
Importance = AndroidImportance.High,
Sound = "rimshot"
});
})
.AddiOS(iOS =>
{
#if IOS
//iOS.SetCustomUserNotificationCenterDelegate(new CustomUserNotificationCenterDelegate());
#endif
});
})
.UseLocalNotificationGeofence();

My NotificationRequest code is:
var notification = new NotificationRequest
{
NotificationId = Convert.ToInt32(sight.SightInGeofence.Id),
Image = { ResourceName = "launcher_40" },
Title = "Sight Nearby!",
Subtitle = "Is the Sight still there?",
Description = "Click the Add Review button.",
CategoryType = NotificationCategoryType.Status,
Android =
{
ChannelId = "",
Priority = AndroidPriority.High,
TimeoutAfter = TimeSpan.FromHours(1),
OnlyAlertOnce = true,
IconSmallName = { ResourceName = "launcher_40" },
IconLargeName = { ResourceName = "launcher_40" },
},
Apple =
{
ShowInNotificationCenter = true,
}
};

notification.Geofence = new NotificationRequestGeofence
{
Center = new NotificationRequestGeofence.Position
{
Latitude = Convert.ToDouble(sight.SightInGeofence.Location_Latitude),
Longitude = Convert.ToDouble(sight.SightInGeofence.Location_Longitude),
},
RadiusInMeters = 30,
NotifyOn = NotificationRequestGeofence.GeofenceNotifyOn.OnEntry | NotificationRequestGeofence.GeofenceNotifyOn.OnExit,
};

Also, my notifications are not showing the Action buttons. I assume it is related to the issue above.

Thanks in advance for your help.

Start with the UseLocalNotificationGeofence registration in MauiProgram.cs and trace how the NotificationRequest geofence creates its Android PendingIntent. Reproduce the geofencing error with the shown request, then verify that the PendingIntent satisfies Android's mutability requirement and that the configured Status category actions appear in the notification.
