This works allright, except for the products with multiple photos.
In that case the magnifier lens is shown only on the last product photo and not on the others, so I suppose is a conflict with some theme css or else.
Thanks for contacting us and choosing our product!
You can go to Appearance -> Customize -> Additional CSS & add this code to resolve the issue with magnifier lens.
However we suggest another solution is go to wp-content/themes/pangja/assets/js/ then open file haru-shop.js
Go to line 68 and remove this code: HARUSHOPMAIN.WooCommerce.singleProductImageZoom();
We’ll notice your case and update in the next version.
