Fail to Create App by WAB on IE 11

Question

I have set up a Portal 10.5.1 server, I have also federated the ArcGIS Server 10.5.1 to the Portal and created maps on Portal.

When I created an app from the map by WAB in IE, the Web AppBuilder just hung, the IE reported the following JS errors:

* Cannot retrieve the property 'value' from undefined or null
* The object does not support the property or method 'startsWith'

But WAB works in Firefox and Chrome. Are there anything missing or I need to configure?

No, IE is version 11 and not in compatibility mode

Mats,

Are you running IE in compatability mode?
