Hi Partner,
It looks like the Unified Interface test is failing between the OpenApp() and OpenSubArea() methods.
It appears that the Sales app that you're targeting may not be based on the new Unified Interface. I've included screenshots below from my own org. The Sales app is NOT the Unified Interface, compared to the Sales Hub which IS the new Unified Interface.
Could you validate based on my screenshots below if you see the same behavior, and if so, whether you observe the same UI differences between Sales and the Sales Hub? If the UI is the same, try changing the following line in your UCI code:
BEFORE
xrmApp.Navigation.OpenApp("Sales");
AFTER
xrmApp.Navigation.OpenApp("Sales Hub");
