There is no notification sound on the mobile phone for Fenxiang sales messages

What you want to ask is why there is no notification sound on Fenxiangxiaike’s mobile phone? The ringtone and alert tone settings are incorrect, and the permission settings are incorrect.

1. The ringtone and alert tone settings are incorrect: This is because the user selected the wrong file or turned off the alert tone and vibration functions when setting the ringtone and alert tone.

2. Incorrect permission settings: Because the user has not been authorized to enjoy sales related permissions, such as notification permissions, the notification sound cannot be issued normally.
