Mobile menu responsive issue

Good morning!

I’m about to launch my site using Highend. The only issue I’m having right now is that on both my iPhone and Samsung Galaxy Notepad the menu icon is a problem while in an upright (portrait) orientation. When moved sideways (Landscape) everything is perfect.

I learned to use WordPress building this site and working with this theme. I think you’ve done a great job making that very easy for me. Thank you!!
