Why can’t Xiaomi Smart Band 8 receive incoming call notifications?

Please confirm whether the incoming call reminder in the App is turned on.
Please confirm whether Mi Fitness App has sufficient permissions, including permission to obtain incoming calls and background running permissions, etc., to ensure that Mi Fitness App can push incoming calls to the band in the background.
Please confirm whether the band is in the following modes: 1. Whether DND mode is turned on; 2. DND synchronization is turned on and DND mode is turned on on the mobile phone; 3. Sleep mode is turned on. Any of the above states will cause the band to not remind you of message notifications.
