I have install the wpml for multi currency. i added a switcher on top of the website but when i change it to EUR, the prices of products are not converting to EUR. It remains with PLN. i think this is problems with the products from ajax products tabs, the products are not updated when the currency is changed.
Please make a full backup of your site and check how it works with some default WordPress themes like TwentyTwenty or WooCommerce Storefront to understand if is it our theme issue or not.
