Broken custom emails plugin

[faishal]

Tried new version 2.2 of the plugin, but the situation is the same. I have got error:

PHP Fatal error:  Call to undefined method WC_Order::get_billing_email() in .........../wp-content/plugins/woo-custom-emails/admin/class-wcemails-instance.php on line 70.

I use WordPress 4.9.4 and woocommerce 2.6.14.

Is this still the case? @faishal
