How to turn on and turn off the background music

You can enable or disable the option of the background music very easily.

In the app preferences page, you will find that option within the Audio preferences section:

When the background music is enabled, the customer will be able to play the music by clicking on the control button in the bottom left corner of the screen.

If the option is disabled, the control button will not appear on the screen, and the customer will not be allowed to play the background music.
