WordPress menu closes too fast on smartphone

Hi currently making a website for a client using the getaway theme. But when I resize my browser to a mobile phone and open the menu it opens and then closes really quickly. I have added in the following code into the theme repo:

jQuery(document).ready(function($) {
   $('.x-nav .menu-item a').off('click');
   $('.x-nav .menu-item a').click(function() {
      return true;

This unfortunately did not work.
the link to the website is leisurely.in any help is greatly appreciated.
