Is there some setting that effects Wolfram Language entity evaluation?

I am trying to follow example from “An Elementary Introduction to the Wolfram Language”, in particular the following:

When I do so I get different output, for instance instead of the entity being displayed in a rounded border box like in book i get:

Entity[“Country”, “UnitedStates”]

And instead of the following outputting a flag graphic as in the book I get:

Entity[“Country”, “UnitedStates”][“Flag”]

I suspect this is some newbie mistake and would appreciate any helpful guidance.

You are not making any mistake: what you see is actually the FullForm of the entity.
Usually the StandardForm is formatted with the rounded box and the fact that you don’t see it—and that you cannot see the flag—probably means you have some issue with the internet connection or with Mathematica using it.
