Disable Mobile Menu, (always show desktop menu)

In your browser, hit F12 to inspect your mobile menu. If you resize your browser between 640px & 641px you can see the different styles being applied. You just need to override the styles for mobile.

Here is what I came up with. Paste these styles in Admin > Appearance > Customize > Additional CSS.

.top-bar .title-area {
    float: left  !important;
}

section.top-bar-section {
    display: inline-block !important;
}    

.top-bar-section li.active:not(.has-form) a:not(.button) {
    padding: 0 21.66667px  !important;
    line-height: 65px  !important; 
}
