[mchanDev]

The code block here, ignores the Yoast settings that disable search indexing of Author archives.

Lines 281 to 316 in 37065d2

	* Co-Authors Plus and Yoast are incompatible where the author archives for guest authors are output as noindex.

The relevant option in Yoast appears to be used here $this->options->get( 'noindex-author-wpseo', false )
https://github.com/Yoast/wordpress-seo/blob/0a1623546fed6266f466035dcf63d41209542060/src/presentations/indexable-author-archive-presentation.php#L121-L124

I believe adding the same options check should address this
