Default currency is not working

Hi there,

I am using this plugin for a while and I had no issues. At now, the plugin is not able to change the default currency by country. I mean:

– if the visitor lands on a Hungarian page or comes from Hungary it should use HUF currency.
– if the visitor lands on an English page and comes from a country except for Hungary, then it should use USD.

Hungarian version: https://llamasters.com/hu/product/llamasters-lamas-party-jatek/
It has a fixed price in HUF, so it isn’t exchanged from the USD.

English version: https://llamasters.com/product/llamasters-the-party-game-sh/

The settings are the same as it was, I only started to test the source of the language recognition because it is stopped working.

I am using a cache plugin: Swift Performance Pro (there is no optimization that causes a problem like merge scripts)
Multilingual plugin: Polylang
