The user from the phone does not see the information. why?

Question

JavaScript

Good afternoon. i have a code

VK.Auth.getLoginStatus(function(response) {
    if (response.session) {-} else {+}
});

This code shows or hides information from the user of the site, depending on whether he is authorized through this browser in VK or not. Everything works fine on the computer, but from the phone, even if you are authorized in the browser, for some reason it gives out that it is not. Tell me how to "undermine" this code for the phone version of the site. Thanks in advance
