Why is there no sound in the new news of the accompanying app group?
1. There is no sound in the new messages of merchants accompanying the app group because there is no voice on the mobile phone system, and there is no prompt sound in the new messages.

2. There is no sound in the new message of the merchants attached to the app group because the group reminder sound in the APP is not turned on. If you find the setting, click the notification message to open it.
