Problem:
The client is experiencing issues with currency shifting and stock updates on their WooCommerce site when NitroPack caching is enabled. The currency selection is supposed to be based on the client's country, but it sometimes fails to change correctly. Additionally, product stock levels are not updating as expected. NitroPack support inquired about the use of variation cookies related to the WooCommerce Multilingual plugin, which the client could not find in the session.

Solution:
1) We confirmed that the necessary cookies for handling languages and currencies already exist, and one of them is a NitroPack cookie.
2) We invited NitroPack to collaborate with us through the Go Global Program to ensure compatibility between our plugins.
3) We provided a code snippet to create a custom cookie for currency:

function wcml_set_custom_currency_cookie( $currency = false ) {<br />if ( is_admin() && !( defined('DOING_AJAX') && DOING_AJAX ) )<br />return;<br />if ( !empty( $currency ) ) {<br />setcookie('wcml_custom_currency_cookie', $currency, time() + 60*60*24*7, '/');<br />return;<br />}<br />if ( empty( $_COOKIE['wcml_custom_currency_cookie'] ) && function_exists( 'get_woocommerce_currency' ) ) {<br />setcookie('wcml_custom_currency_cookie', get_woocommerce_currency(), time() + 60*60*24*7, '/');<br />}<br />}<br />add_action('wcml_switch_currency', 'wcml_set_custom_currency_cookie');<br />add_action('init', 'wcml_set_custom_currency_cookie');

4) We advised the client to add this code to their functions.php file and to ask NitroPack how to exclude the 'wcml_custom_currency_cookie' from caching.
