Notification Cleaner is hiding my desired notifications. How can I fix this?

It’s possible that you accidentally activated the Notification Cleaner feature in dfndr security which turned off your notification alerts.

To disable this feature and receive all notifications again, please follow these steps:

  1. Open the dfndr security app and tap on Tools;
  2. Scroll down to Notification Cleaner (click from a smartphone);
  3. Tap on Hidden
  4. If you want to unblock all notifications, tap on the button next to “Make all apps alerts visible” and select Yes.
    If you want to unblock a specific notification, just tap on the Visible button next to the app from which you want to receive the notification.

Notification cleaner has now been disabled and you will receive notifications for all apps on your device again.
