Notification badges don't appear when using Mobile Notifications

I’m implementing local push notifications,

AndroidNotificationCenter.SendNotification(new AndroidNotification
{
    Title = title,
    Text = body,
    SmallIcon = "icon_0",
    LargeIcon = "icon_1",
    FireTime = System.DateTime.Now.AddSeconds(afterSec),
    Number = 1
}, ChannelId);

Even if you set the number to Number like this, the badge will not be displayed.
Also, there is no push notification on the terminal itself.

On iOS, I was able to set a number in “iOSNotificationCenter.ApplicationBadge” and display the badge,
Is there any other place to set?

Initialization is performed as follows.

AndroidNotificationCenter.RegisterNotificationChannel(
    new AndroidNotificationChannel
    {
        Id = ChannelId,
        Name = "Default ChannelName",
        Importance = Importance.High,
        Description = "Channel Description",
    });

Hey,

Thank you for posting this. It does seem to be an issue, which will have to be addressed. Could you post us some extra info, such as:
• Device that reproduces the issue
• Device’s Android version
• Mobile Notifications version that you’re using

Hey Max,
Before doing that, I’d also recommend checking your notification channel settings in App Info section on your device. Do check if the App Icon Badges are enabled for each channel that you’re using
