Great App. But Surveillance notification doesn't work anymore. I just figured out now but it seems to be a 6 months old issue. Huawei P30 Android App, last version, and all the setting are ON for notifications (in app and in phone settings) 2 years later, the notification system keeps not working. I remove one star for that again until the developer of the app does something. I have a surveillance system that doesn't push notification, it's useless.
