Why aren't css rules applied on smartphone?

Question

css

Good afternoon.
Faced the following problem. On mobile devices, css rules do not work, in particular display:none; but this behavior is not present in all browsers. On desktops, when the browser window is reduced, everything is clear. Yandex browser, Chrome is installed on the mobile and everything works on them. And on (as I understand it) the built-in does not work. I have found this issue on the forums but have not found a solution. Can you please help me understand what is the reason for this behavior?
Website address: frogishop.ru (Problem with the logo, both standard and mobile versions are displayed).
I checked the display:none property on the caniuse.com website; in all browsers after the age of 13 should work. The honor7c phone is a fairly recent model, it is unlikely that there is an ancient browser there (I don’t know how to find out which one). + tried to hide the element with visibility and width:0 properties. Nothing helps
