Why does changing currency based on shipping address occur in e-commerce?

[InfuseNotBrew]

Why oh why does Shopify think that changing currency based on shipping address is a good idea?!  This automation (seemingly switched on in late 2023 from what I can gather) means that a UK customer cannot send a gift to a German friend without paying in Euros, just because we have the tenacity to offer Euros as a payment method for German customers.

What insane short-sightedness led to this decision?  Why weren't we told, and just left to find out via our customer's wrath?  Why can't we choose to turn this off, or make it work via billing address?

We're a highly giftable company and we're losing customers daily who email in asking why they're billed in the shipping address currency and not billing address currency.

I have the same exact question, this makes no sense for anyone selling gifts. Is this some sort of option in the other more expensive shopify plans?
