Why is the Adsense block not displayed on a smartphone?

Question

JavaScript

Hey!
I can't figure out why the ad block code is not displayed on smartphones:

<style>
    .class_name { width: 336px; height: 280px; }
    @media(min-width: 580px) { .class_name { width: 580px; height: 400px; } }
</style>
<div style="display: block; margin: 5px 0;">
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- Netboard -->
<ins class="adsbygoogle class_name"
data-ad-client="ca-pub-XXXXXXXXXXXXX"
data-ad-slot="XXXXXXXXXXX"</ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script></div>

At the same time, it works perfectly on the desktop - at high resolution it is displayed in sizes of 580x400, when the browser page is reloaded with a minimum width, 336x280 is loaded. On any smartphone, the block is not loaded at all. What can be wrong?

Maybe you need to wait, I had similar problems with him for a long time, I waited, then everything appeared, about mobile phones, maybe the same thing?
