No menu present on mobile device

I cannot get the Primary Menu to show on a mobile device. I have checked similar threads and can not seem to see a solution for the problem. HELP.

Hello there,

Your header color on mobile screen is white, and since the default color of mobile menu button is white as well, it isn’t appeared. You should color it becomes darker. It can be done by adding the below CSS code to Appearance > Customize > Additional CSS from dashboard.

    .btn-menu {
      color: #000;
