It sure is

They seem to be replacing "somewhat working" functionality that's more directly related to systems under the hood with superficial screens that don't map to what's underneath. All looks pretty, but eventually throws you into the old workflow and then completely fails (i.e. the new cancel/change selector accessible from the "existing reservations" screen, or the new booking interface).

I used to really appreciate how clear and effective the site was, compared to many other airlines. A few years of this, and UA site will be as useful as Air China.
