I'm using Windows 10 Home version 1809 with Microsoft Edge version 44.17763.1.0 with absolutely zero problems on the GOG site redesign.

I moved from Chrome to Edge and been pretty damn happy with the browser so far. only issue is it does not run as amazingly fast as it did the first day I used it. very odd but eh maybe it was all those major updates that did something and I have to re install windows.
