WooCommerce Payments - Multi-currency switcher not changing correctly on the front-end

Overview of the issue

WooCommerce Multilingual brings a whole set of options with its multi-currency feature. However, if you use it together with WooCommerce Payments and its multi-currency system, you will see some conflicts. For example, if you change a currency in the front-end, the amount changes but not the currency symbol.

Workaround

To avoid this, please select only one multi-currency system. To disable the one offered by WooCommerce Payments, please go to Payments → Settings → Advanced settings, scroll to the bottom of the page, and uncheck it.
