Why is the Xiaomi Smart Band 9 Pro not receiving messages after pairing with an Android phone?

If the Xiaomi Smart Band 9 Pro is not receiving messages after pairing with an Android phone, it can be due to insufficient permissions for the Mi Fitness APP. The APP requires certain permissions to function properly and relay notifications to the band. To enable the necessary permissions, please refer to the following methods:
1. During the initial pairing, follow the prompts to allow background permissions;
2. After pairing, you can go to the [Mi Fitness] APP >> [Device] >> [Notifications and calls] >> [App notifications] >> enable [Mirror phone notifications] or [Customize notifications] and follow the instructions there to adjust the settings as needed.
