Why can't the calendar widget be added to the home screen on the Xiaomi 15T Pro?

Thank you for your support of Xiaomi. In MIUI version 13.33.38, a system issue prevents the Calendar widget from being added to the home screen. When attempting to place the widget, it may not appear or remain in the designated area, which restricts home screen customization.
This behavior is related to a software compatibility issue in that specific version and does not indicate a problem with the device or the Calendar App itself. The system update resolves the underlying issue by restoring proper widget placement.
To ensure an optimal experience, please refer to the following information:
  1. Please ensure your phone is connected to Wi-Fi.
  2. After updating to version 13.33.39, you will be able to add the widget normally.
