Set up a new user recently and they are getting the old UI with the Left expanding menu. (see attached) Can't seem to locate how to update to current.
Awesome. Thanks for the reply Sagi. That was it.
The left menu is because the user is opted for Personalized Navigation. You need to un-select this option and then the left menu will no longer appear, see for more info:
