Problem:
The client is trying to implement a manual currency switcher on the top bar of their website but it is not visible. They are using the

do_action('wcml_currency_switcher', array('format' => '%name% (%symbol%)'));

in the section of header.php and also tried the shortcode [currency_switcher] on a random page, but neither method displays the switcher.

Solution:
We recommend checking the WooCommerce Multilingual’s multi-currency feature documentation here: https://wpml.org/documentation/related-projects/woocommerce-multilingual/multi-currency-support-woocommerce/
Ensure that the currency switcher is added using either a widget or a shortcode. More information about how to implement the currency switcher can be found here: https://wpml.org/documentation/related-projects/woocommerce-multilingual/multi-currency-support-woocommerce/#currency-switcher-shortcode
Additionally, the issue might be due to the settings where only one currency per language is enabled, which means the switcher won't display if there's nothing to switch to. Enabling multiple currencies for each language could resolve this issue.
