Custom ad code not working

Hello.
I am trying to place Ezoic code wrapped around Adsense code on my AMP pages using your custom code option.

This is how the code looks.

<!-- Ezoic - mid_content - mid_content -->
<div id="ezoic-pub-ad-placeholder-138">
<!-- Responsive_MTF_Img_Txt_Windows -->
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-6837307237823202"
     data-ad-slot="5919375084"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>
</div>
<!-- End Ezoic - mid_content - mid_content -->

But it is not working on my AMP pages.
What should I do.

The page I need help with: [log in to see the link]
