Problem with image zoom on mobile

Hi
I′m having some troubles with the zoom effect I created on https://gallerisandberg.dk/
It′s been added to sites such as this: https://gallerisandberg.dk/kunstvaerker/olga/

However when visiting the site from mobile the zoom effect is creating problems. It′s works but it is not possible to click any items on the page such as the menu. Whenever we try to click on the burger-menu in the top right corner the zoom effect “takes over” so we aren′t able to leave the page because everytime we click on something it just zooms.

We′ve had to disable the image zoom for now since it′s impossible to visit these pages and leave them again due to zoom.

Do you have any experience with this problem and know how to fix it? Or is it possible perhaps just to disable zoom for mobile devices? It could be an okay solution for us just to have the effect on desktop and tablet. However it would be best if it worked on all devices.

Thanks.
