在amp-mode-touch上没有广告加载

Question

就像标题所说的那样。我已成功在我的AMP帖子上放置了adsense广告。在通过firebug在我的桌面上进行测试时，广告正按计划进行。但是，我的手机无法播放任何广告？页面正文类更改为amp-mode-touch，广告div容器完全消失。

以下是一个示例网址 - http://www.gamersgreed.com/kingdom-come-deliverance-fps-boost-optimization/amp

以下是我用来制作广告的代码 -

//Insert ads after third and seventh paragraph of any single post content.

add_filter( 'the_content', 'prefix_insert_post_ads' );

function prefix_insert_post_ads( $content ) {

    $ad_code = '<div style="text-align: center;"><amp-ad width=300         height=250
type="adsense"
data-ad-client="ca-pub-7568065840567088"
data-ad-slot="1234194857">
<div placeholder></div>
<div fallback></div>
</amp-ad>
</div>
';

$ad_code2 = $ad_code;

if ( is_single() && ! is_admin() ) {
   $content = prefix_insert_after_paragraph( $ad_code, 2, $content );
   $content = prefix_insert_after_paragraph( $ad_code2, 7, $content );

return $content;
}
return $content;
}

// Parent Function that makes the magic happen

function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content     ) {
$closing_p = '</p>';
$paragraphs = explode( $closing_p, $content );
foreach ($paragraphs as $index => $paragraph) {

    if ( trim( $paragraph ) ) {
        $paragraphs[$index] .= $closing_p;
    }

    if ( $paragraph_id == $index + 1 ) {
        $paragraphs[$index] .= $insertion;
    }
}

return implode( '', $paragraphs );
}
