Why is there no schedule for Huawei's mobile phone setting schedule reminder?

If there is no reminder when the mobile phone calendar arrives, it may be that you don't have permission to open the calendar notification. We need to open all notification permissions in Settings-Notifications-Calendar. Calendar reminders can be set in Huawei mobile phones. Just open the calendar, click+to add a schedule and set the reminder time.

In addition, Huawei mobile phones can also use other third-party calendar reminder tools, and cloud notes can set up to-do regular reminders, repeated reminders, important reminders and Gregorian calendar lunar reminders. And after the specified time, cloud notes can not only send reminders through ringtones and pop-ups, but also bind WeChat, nail reminders, open SMS, voice calls, calendar reminders, and synchronize reminders in various ways.
