I just want to add that I tried both option of “Prices and Currencies By Country” and “Multicurrency Switcher” independently and in both situations the situation happened. Once the product is added to cart, the price would inflate by the exchange rate again. This is a big issue for me. Without this working, the other features of this plugin are not as important to me. Crazy how the product price gets inflated once added to cart. I really need a fix on this soon please.
