We have a worldwide e-commerce website. We offer products in multi-languages and currencies.
The default currency converter is not user-friendly (Design editing is limited: specially corner radius), and it doesn't automatically detect the currency according to the user's location. Users need to choose it every time, even when they select, close the browser, and re-open it again. It also has a bug. Sometimes when the user selects a different currency and clicks on products, it becomes a default currency again.
