Hi,
There is a very annoying bug in the theme in regards to the mobile menu.
It is present in your demos too.
If you open the mobile menu and then close it but clicking anywhere else besides the actual close button button it will also click on the elements that are under the overlay
The best way to test and understand what happens is on a product page
Go on a product and then open the menu. Then click away from the menu but not on the close button. You will notice that it will register a click on the big product image and open the lightbox.
Here is a screenshot : https://prnt.sc/sJlmBEdMlwsf
Click on an area i marked with a blue X
You should modify it so that it will not register clicks on the elements under the overlay.
For example, this does NOT happen with the offcanvas filters. Only with the menu
Thank you
Claudiu
