I haven't looked into this closely but can see that in the Home class component's componentDidUpdate method, it's relying upon a URLSearchParams instance, which MDN Web Docs indicate is not implemented in Internet Explorer, and will soon be marked deprecated in other browsers.
May also be unsupported by iOS.
This code is (as best as I can tell, I haven't looked very closely) responsible for extracting the "pair" query string from the URI, e.g. after someone clicks on a pair beneath the ExchangeWidget.
