What to do if the Xiaomi Smart Band 9 can't access to music of the phone?

For your reference, please check the following methods:
1. Check whether the APP has enabled notification permissions correctly. If it is the latest system of Xiaomi phone, please go to [Settings] >> [Privacy] >> [Permission manager] >> [Notifications] >> navigate to [Mi Fitness] APP >> turn it off and then turn it on;
2. Confirm whether the music player of your phone is turned on, and whether Mi Fitness APP is connected to your band;
3. If only a certain music APP cannot be controlled, it is recommended to reinstall that APP and try again. At present, this function supports most of the music APPs on the market. However, the openness of the music player and the different APP versions will affect the experience of this function to a certain extent.
