There is a workobject assignment link which indicates the place where the workobject is there.
On click of that link, it proceeds further with a different screen. The link is not clickable in IE11 whereas its clickable in Chrome and I can progress properly till the end. Although, the clickable hand symbol is coming.
Another issue in IE11, the portals are disappearing under Launch sometimes. On refresh, it comes back again.
Moreover, the screen performance is very poor in IE11 during navigation.
