Bootstrap responsive design not working, what to do?

Question

css

Good afternoon.
Faced the following problem.
Site on symfony
Designed by Bootstrap
The template turned out to be rubbery and works correctly. when you change the width of the browser, everything shrinks and the columns crawl as they should.
But there is one thing but ..... On the phone (Smartphone androyd), the categorical does not want to switch to a compressed version for this resolution. Namely, it displays the full version as if you were just watching from a regular computer.
I tried using this method

<meta name="viewport" content="width=device-width, initial-scale=1.0">
        <link rel="stylesheet" href="{{ asset('css/bootstrap.min.css') }}">
        <link rel="stylesheet" href="{{ asset('css/bootstrap-theme.min.css') }}">

But "viewport" did not give me any result ... I shoveled a bunch of everything on the Internet, but there is no other solution but
Tell me what to do and how to be? where to look for a problem at least ...
Thanks in advance for advice on solving this problem
