Hello sir,
I'm using zara theme and i'm facing some responsive issue on my item page. Just for example when you go to this link https://merowish.com/mobiles-tab-s/mobile-phones/xiaomi-redmi-note-3-32-gb3-gb-ram-like-new_i214 of my website then you can see this issue on Opera Browser of mobile mainly it shows this responsive issue.. the page moves left and right. Littile bit like zoom in - zoom out. Here i had given a google drive link you can see this screen record to be more clear
