I've got a custom site that uses the API/SDK to display the Shopify products and add things to a checkout that is all working fine.
The site now needs to have multiple currencies so I'm fetching the enabled currencies from the shop payment settings and adding those to a currency switcher on the site. The problem I'm now having is that when someone changes the currency and they already have things added to a checkout I can't see any way to change the currency of the checkout. Even if I try to create a new one with the correct currency I end up with the original currency.
Any help is much appreciated.
