Im experiencing an Type Error Issue in my iOS 12

[lilsizzo]

Whenever the flexslider is clicked, this error is showing in Safari. TypeError: undefined is not an object (evaluating '$obj.pause'). There are 2 flexsliders that are synced.

$('.stage__large .flexslider').flexslider({ animation: "slide", controlNav: false, animationLoop: false, slideshow: false, sync: stageSmall, smoothHeight: true, animateHeight: true, directionNav: false, touch: true, start: function() {

            },
            before: function(slider){
                
            },
            
        });
