Hi All,
Thanks for replying to this question. I figured out what the issue was.
As pointed out in some replies in this thread, the feature must be first enabled in the feature management page.
The strange behavior that's happening though is that if you access the "Adjust exchange rates" task using the "Search" function, it takes you to the old page where the new features are not visible somehow. However, if you navigate to "Currencies" page and run the "Adjust exchange rate" task from this page, then you are able to see all the new features as well.
I guess its the menu item that isn't coded properly.
