Sync all post meta except some

Hello Chouby,
I just tried pll_copy_post_metas filter from your documentation but it doesn’t do what I need.

What I just need is to Sync all Custom Meta except some that needed to be translated separately.

Thank you in advance

UPDATE:

Done with that:

add_filter('pll_copy_post_metas', 'copy_post_metas');

function copy_post_metas( $metas ) {

	if(($key = array_search( 'main_title', $metas ) ) !== false) {
		unset($metas[$key]);
	}

	if(($key = array_search( 'subtitle', $metas ) ) !== false) {
		unset($metas[$key]);
	}

	return $metas;

}

It’s not very clean but it works
