low Priority metabox function

The low priority meta box function no longer works with the new version. Is there a replacement function that works with the new version?
Thanks.

function lower_aioseop_priority( $html ) {
    return 'low';
}
add_filter( 'aioseop_post_metabox_priority', 'lower_aioseop_priority' );

also tried:

function lower_aioseo_priority( $html ) {
    return 'low';
}
add_filter( 'aioseo_post_metabox_priority', 'lower_aioseo_priority' );
