How to AMP Auto ads (beta)

Hey Guys,

I am using the Advance AMP Ads Plugin to insert Ads on my AMP pages. Recently, I got an Email about trying AMP Auto Ads on my website.

Here is the Implementation Guide

By Visiting the “Advance Settings” on AMP Plugin, I added Header and Body Codes as suggest by Google.

Then, I added <amp-auto-ads> to Below the Post Content (Single Post, Custom Advertisement) in order show the Ads on all pages.

The Plugin’s output on AMP Pages is: <amp-auto-ads class="i-amphtml-element i-amphtml-notbuilt amp-notbuilt i-amphtml-layout-container"></amp-auto-ads>

Beause of this reason, I am unable to try the new AMP Ads. Kindly, help me to resolve the issue.
