Adsense Ads not showing

Hello.

I have added the code as per the instructions and looking at the Source Code for the page, I see that the AdSense code is being added correctly but nothing is displaying.

This is the AdSense code that I am adding:

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-4464664050302082"
     data-ad-slot="66565963450"
     data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

Do I have to do anything inside my Google account to “activate” this so it starts showing or not…??

Thanks in advance.
