This is an issue strictly on mobile landscape breakpoint.
On published site, when we view the homepage on an actual mobile in landscape mode, the page just reloads when we press the menu button 
when the mobile menu is suppose to open.
When we preview inside the visual editor, on mobile landscape breakpoint, everything works.
We have no idea what’s causing this issue despite our investigative effort.
Can someone help us resolve this please? Thank you!!
