How to smooth scroll in Squarespace 7.1

Hi im trying to add an anchor link into my website and want it to smooth scroll to it. Unfortunately I cannot find a way to make it work with safari, it works with chrome

I have enabled smooth scroll in Design > Custom CSS

Did you ever find a solution? I found the following. It works to smooth scroll in Safari and Chrome, but the problem is that it has bugs when on mobile. When you are vertical and you click a link in the dropdown hamburger menu, the menu gets stuck at the top of the site and the website seems to be frozen. 

SMOOTH SCOLL (works in both Chrome and Safari but gives bugs to safari mobile)

CSS injection

html {

scroll-behavior: smooth;

}

Header Injection 

<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>

Footer Injection

<!-- smooth scrolling -->

     <script type="text/javascript">

      $(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>

Ok I got a solution! It isn't free though. I had this add on before but it bugged out recently. I was working with their support team and got it all ironed out. Works in mobile, safari, chrome and all.
