Why is there no sound in the rural commercial bank?

First of all, we need to set up a voice broadcast reminder function on the collection APP, and log in to a treasure as an example.

Enter more and find merchant services under the fund exchange column.

Click Settings-Voice Reminder in the upper right corner to open the QR code voice reminder switch for receipt.

After confirming that voice reminder has been turned on, there is still no sound. Maybe the APP version is too low. We need to confirm whether the mobile APP we collected has been upgraded to the latest version.

It is also possible that the volume of the mobile phone itself is too low to hear. In this case, just turn up the phone volume.
