I attempted to use anchor links to navigate a single page theme (e.g., "/#pagename").
This worked on desktop resolutions, but the mobile navigation would not register the click and send the user to the anchor. It simply closed the menu.
I overwrote the normal anchor behavior by using CSS Tricks "Smooth Scrolling" inside my Site Footer Injection:

 <script>
   $(function() {
     $('a[href*="#"]:not([href="#"])').click(function() {
       if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
         var target = $(this.hash);
         target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
         if (target.length) {
           $('html, body').animate({
             scrollTop: target.offset().top
           }, 1000);
           return false;
         }
       }
     });
   });
 </script>



This fixes the issue.
