WebPlayer UnityObject2.getUnity().SendMessage() method is missed in IE 11

Dom element OBJECT returned by getUnity() not contains SendMessage.
How i can use SendMessage in IE?

Can you please file a bug report with a minimal repro project and ping me the case number here?
Thanks.

I found that while you can’t check for the existence of SendMessage in IE, you can still call the method. It’s unfortunate that you can’t test for the method, but this may be a limitation of IE and not a UWP bug.

typeof uo.SendMessage; // -> "unknown"

uo.SendMessage("foo"); // -> "Invalid number of parameters"

At least in the second case we get a message from the plugin which was expecting three parameters, indicating that SendMessage is actually working.

Hope this helps!
