You need to ensure that you have enabled notification permissions on your phone and the Xiaomi Home App, so that you can receive notifications from home surveillance of the Xiaomi Smart Camera C201.
To enable the notification permissions on the phone and the App, please refer to the following steps:
Please go to [Settings] on your phone >> access [App notifications] >> open the notification permission of the Xiaomi Home App.
In the Xiaomi Home App, navigate to [Profile] >> [Additional settings] >> [Notification settings] >> to keep the switch of the [Device notification] settings open.
Enabling both settings guarantees timely delivery of notifications for better home surveillance.
