Currency not change

Hello,
I have just installed and configured your module on my client’s website forward-wip.com, but the currency switch is not working.

There are currently 5 currencies on the website, but whenever I try to switch to another one, it always reverts back to the default Euro currency. Moreover, on the product pages, the price remains in Euros.

I would like the currency to be automatically set based on the user’s country. Also, when a customer manually changes the currency, it should update the product prices accordingly.

The website is built with Elementor and WooCommerce.
Prices are fixed (by the way, I don’t see the fields for entering prices in other currencies on the product page).
I have deactivated the WP Rocket cache module.
