Why isn't my code changes reflecting on mobile view?

Hello, since a few hours ago the changes in the code are not reflected on phones, only on computers. For example, on the computer the border of the add to cart button is visible, but not on the mobile. Also the product image and description image lines borders are not hidden on mobile devices. On the computer they are hidden. Please help me as soon as possible. My url is: https://lelaloot.com/
