Adding aditional Content to Email String translation

[MELindley]

Can you reproduce this issue on default Wordpress theme (eg Storefront)?

Yes:
The additional content for emails is not added to string translations

Can you reproduce this issue when all other plugins are disabled except WooCommerce, Polylang and Hyyan WooCommerce Polylang Integration?

Yes

What product versions and settings are you using when this issue occurs?

• PHP: 7.2
• WordPress: 5.2.3
• WooCommerce: 3.7
• Polylang: free
• Hyyan WooCommerce Polylang Integration: 1.4.3
• Browser: All

I have added the additional_content field to the string translation by rewritting

public function registerString($email_type, $sufix = '') 

and adding

if (isset($settings['additional_content' . $sufix])) {
    pll_register_string('woocommerce_' . $email_type . '_additional_content' . $sufix, $settings['additional_content' . $sufix], __('WooCommerce Emails', 'woo-poly-integration'));
} 

after the recipient field

It's a pretty easy fix, let me know if I should submit a pull request to add the feature :)

yes you are correct there are some email related enhancements in recent woo commerce releases which are not yet added to the plugin, you are welcome to submit pull request

I've added this in development and will check in after fixing a few related issues.
It's a complex subject so adding a note on it here: https://github.com/hyyan/woo-poly-integration/wiki/Email-Languages
