Remove price from loop & product page

add_action('wp', function(){
    remove_action('reycore/woocommerce/after_shop_loop_item', 'woocommerce_template_loop_price', 10);
    remove_action('woocommerce_after_shop_loop_item', 'woocommerce_template_loop_price', 60);
    remove_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10);
    remove_action('woocommerce_single_product_summary', 'woocommerce_template_single_price', 10);
});

Add WooCommerce Multilingual Currency Switcher into Default Header

// Adds the currency switcher in the header
add_action('rey/header/row', function(){

    // This shortcode adds the Currency switcher
    // but too much text is shown
    //echo do_shortcode('[currency_switcher]');

    // instead show only what matters
    do_action('wcml_currency_switcher', array(
        'format' => '%code% (%symbol%)'
    ));

}, 70);

And also some fine tuning CSS in Customizer > Additional CSS

.wcml_currency_switcher {
    margin-left: 1.5rem;
    width: auto;
}

These codes apply for the Default header, when it’s non Global Section. If you’re using a Header Global Section, simply add a Shortcode element into the Header section and paste the shortcode eg: [currency_switcher] .
