Why doesn't the calendar of Huawei nova8pro show the schedule?

The schedule may be saved under the corresponding account.

1, so we need to open an account first. After we enter the calendar, click the three buttons in the upper right corner.

2. Then click Calendar Account Management, and we will open the corresponding calendar to display the schedule later.

3. In addition, you can directly use cloud post-it notes to add post-it notes and set reminders.

Still can't solve the problem and restore Huawei's desktop data.
