Why don't shadows render in edge browser?

I have setup a simple game with a landscape and an object set on top of it. There is a directional light in my scene which is casting shadows and everything looks great in the editor, in desktop builds and in html5 using chrome but when I load the html 5 build using Edge, The shadows are missing. I have tried making the light static and also stationary but neither of these changed anything. I’m new to UE and this is my first time working with lighting.
