How to hide Author Name?

If you haven’t already found it, try this suggestion
https://github.com/Automattic/facebook-instant-articles-wp/issues/439

function tk_instant_articles_authors( $authors, $post_id) {
	$authors = array();
    return $authors;
}
add_filter('instant_articles_authors', 'tk_instant_articles_authors', 10, 2);

Thanks, it worked ??
