showing no popup/notification when channel_id of message is populated

[curelom]

I've setup several channels in the app. When I send a message without a channel id, the message is received and I also get a phone popup. If I add a channel id, I still receive the message, but no phone popup.

if (Build.VERSION.SdkInt >= Android.OS.BuildVersionCodes.O) { //Change for your default notification channel id here AzurePushNotificationManager.DefaultNotificationChannelId = NotificationConstants.NOTIFICATION_CHANNEL_ID;

            //Change for your default notification channel name here
            AzurePushNotificationManager.DefaultNotificationChannelName = "General";

            NotificationManager notificationManager = (NotificationManager)GetSystemService(Android.Content.Context.NotificationService);

            notificationManager.CreateNotificationChannel(new NotificationChannel(
                    NotificationConstants.NOTIFICATION_MAILERS_CHANNEL_ID,
                    "Mailers",
                    NotificationImportance.High));

            notificationManager.CreateNotificationChannel(new NotificationChannel(
                NotificationConstants.NOTIFICATION_REMINDER_CHANNEL_ID,
                "Reminders",
                NotificationImportance.High));
        }
