My edge had same issue for a while now, and i've been using brave (which is basically chrome) for a while now and that works just fine. I thought it was me issue, because it used to run in edge and i wouldn't have thought that they changed the code, and usually web developers check these things before launching updates. But apparently they didn't.
It wouldn't have been an issue before, but edge is an actually good browser these days and been as my default browser for a while now.
What's strange is that Edge is practically the same browser as Chrome (that's why Chrome extensions work in Edge) so it's weird that stuff work on Chrome and not on Edge. I remember that it was working without a problem last month when I was writing my review of the MonkeyTilt. I guess that they changed something that broke the website on Edge.
