After adding this topic, I realized I probably already know the answer to my own question. Since the Yoast AMP plugin just connects to the WordPress AMP plugin and allows you to control design features, then I would need to add the AdSense code to the WordPress AMP plugin template, which I know from previous experience is single.php.
I’m about to test this theory and hopefully it will work. Just figured I’d post an update, in case anyone else had the same question.
