I have found that you are using the oldest version of the theme. I have updated the theme and theme plugins on your site, now please update all other 3rd party plugins on the site then check the issue on ios devices. I am sure your issue will be solved.

– hamburger menu not click

– image not show in some position
*** all issue above is happen on first open website on mobile device
