Open issue
We understand that multi-currency checkout is an important feature for many of our merchants. Discount Ninja has opened an issue with Shopify to correct this issue.
The app passes the required values (presentment currency) to the checkout to allow Shopify to create the checkout using the currency selected by the visitor. Unfortunately, there is a defect in Shopify's Checkout API that causes the checkout to ignore the presentment currency.
Shopify was notified of this issue on October 5th 2019.
Our latest tests (executed in Q2 2021) show the issue is yet to be resolved.
