"Accessing Workfront through Adobe Experience Cloud gives you a seamless, unified experience for managing all of your Adobe applications. Single identity management gives you one place to log in, without multiple URLs or login IDs."
This update that was rolled back yesterday seems like it will be happening again soon. The "new Workfront experience" as well as this added toolbar takes up so much screen real estate that it makes a second monitor a necessity to use Workfront. Our users are all comfortable to continue to use multiple tabs/windows to switch between other Adobe products that we have.
When this was rolled out yesterday, many users directed complaints to our admin team.
