Hi,
Sorry for the delay. I’m sorry, we have to improve this detail yet.
Please try it like this for now:
1 – Create a new order manually accessing WooCommerce > Orders > Add Order
2 – Change the order currency and click save
3 – Now go to your site on frontend and switch to the same currency
4 – Now you can go back to your order and if you add a new item, the price will be correct. Old items will not change price, only the new ones
