We no longer maintain a list of specific supported browsers - instead, we work on the basis of supporting any "modern" browser.
We explicitly test in:
Chrome - Windows, Android and Mac
Firefox - Windows and Mac
Safari - Mac and iOS
Microsoft Edge - Windows
Please note: older versions of Internet Explorer may function but may have some unexpected display issues caused by how IE handles certain CSS styling elements. This is not something we will be able to support and recommend upgrading to IE 11, Edge or another browser platform.
