Just happen to see this article, I have a similar problem here. Need your help : )
We sell in over 5 countries including UK, US, CA… And we’re now using ‘currency convert in vitals app’ & ‘shopify payment’ to support the multi-currency based on user’s IP.
But it’s difficult to set shipping rates because only USD is supported in shopify shipping profile.
For example i set free-shipping over 50 USD amount (about equals to 36.15 GBP), it’s not easy to tell UK users about this, with no rounding expression.
And the most difficult part is when the market currency rate float, sometimes a same order for example in 49.99 USD will be paid-shipping , but become free-shipping when it switched to GBP.
Do you have any advice here ?
