WordPress, WooCommerce. Change of price and currency on checkout?

Question

CMS

There is a site on woocommerce. Works in 3 countries and there is a country switch on the pages. Switched the country - the price with currency has changed. Works correctly.

But if the country does not match the country of the order, then the country selection is added on the checkout. It is necessary to make sure that when you change the country in the checkout, the price + currency of the goods would also change there. Now with the WooCommerce Price Based on Country plugin, this does not work correctly, although it is configured. That is, when choosing a country on checkout, it should work like choosing a flag from above, so that the price and currency change right there.

How can this be fixed?
