If you use the calendar app with the Huawei P20 Pro and enter many appointments, reminders and birthdays there, you will receive a notification each time.
This should at least be the case. If you do not receive calendar notifications, you can activate the notifications for the calendar app.
You can do this as follows:
1. Open the calendar app on the Huawei P20 Pro.
2. Now select "Settings" in the sidebar to display the calendar options
3. Here you see the option "Notifications" - Activate it with the help of the slider - Done!
If you prefer to deactivate the notifications, the controller must of course be set to "inactive" here.
You now know how to activate or deactivate the notifications for the calendar app on the Huawei P20 Pro.
