Disable Primary Navigation on Tag Conditional

I have a plugin that allows pages to have tags and i want to disable the primary navigation menu with all pages tagged with the term "podcast".

add_filter( 'generate_navigation_location','tu_move_navigation' );
function tu_move_navigation( $location )
{
	if ( has_term( 'podcast' ) ) {
		return '';
        }
	
	return $location;
}

For some reason this is not working for me.
