Remove Author Link Issue

I tried the code per your documentation at https://docs.themeisle.com/article/942-in-feedzy-how-do-i#remove-links to remove the author link, but it doesn’t work. However the other filters (thumbnail and title) do work.

The code used:

//Remove the author link
function bweb_feedzy_remove_link_matches( $matches ) {
? return $matches[2];
}
function bweb_feedzy_remove_link( $content, $feedURL ) {
? $pattern= '/<a.*href=\"(https?:\/\/.*)\".*>(.*)<\/a>/iU';
? $content= preg_replace_callback( $pattern, 'bweb_feedzy_remove_link_matches', $content );
? return $content;
}
add_filter( 'feedzy_meta_output', 'bweb_feedzy_remove_link', 9, 2 );

Has the filter changed?
