Currency dont switch

We are using WooCommerce Multi Currency (CURCY Premium) together with TranslatePress.
It used to work correctly for a long time: switching the site language also switched the currency (CZ = CZK, SK = EUR, PL = PLN, …).

Now the behavior changed without any modifications on our side:

On the first page load, CZK is displayed (default currency).

When switching the language, the currency switches to EUR.

From that moment on, EUR remains locked for all languages, even if we switch back to CZ or to any other language.

In Location → TranslatePress Multilingual all languages are correctly mapped to their currencies.

Clearing cache, testing with None/AJAX/JSON, incognito mode → no effect.

Summary:
CURCY now only responds to the first switch, stores the currency in the cookie, and no longer changes it when switching languages. We need the currency to always switch according to the currently selected language, as it worked before.
