I’m using the following code from your support thread to close the mobile menu when a link is clicked
(function($){
$('.x-navbar .x-nav-wrap.mobile a').on('touchend click', function(){
$('.x-btn-navbar').click();
});
})(jQuery);
However, after the link in the mobile menu has been clicked and the menu has closed as desired, the hamburger menu requires two clicks to open again.
