[Resuelto] Changing to a different currency(CHF) makes the minicart show EUR instead of CHF

Background of the issue:
I am trying to change the currency to CHF, add a product to the cart, and have the right currency shown in the mini cart (CHF). The issue can be seen on this page: enlace oculto

Symptoms:
Changing to a different currency (CHF) makes the minicart show EUR instead of CHF. Refreshing the page solves this.

Questions:
Why does the minicart show EUR instead of CHF when I change the currency?
How can I ensure the minicart displays the correct currency (CHF) without needing to refresh the page?
