Please upgrade to version 1.4.5 (just released it)

Why would you want to change this attribute?

@shaharfried Please send a link to the mirror site.

Can’t help you without additional information.
Try reading more about debugging in wordpress.

Yes, it can be done.

Something like that:

add_filter( 'wc_zap_mirror_wp_query', function( $args ) {
	$args['meta_query'] = array(
		'relation' => 'AND',
		array(
			'key'     => '_stock_status',
			'value'   => 'instock',
			'compare' => '=',
		),
		array(
			'relation' => 'OR',
			array(
				'key'     	=> '_wc_zap_disable',
				'value'		=> 'yes',
				'compare' 	=> '!='
			),
			array(
				'key' 		=> '_wc_zap_disable',
				'compare' 	=> 'NOT EXISTS'
			)
		)
	);
	return $args;
} );
