Hi Catherine,
Did you create a program of the Type "Email Program" rather than default, event or engagement? This would give you the Control Panel that you see in the community article you referenced. Some of the other screens may look different as we are in the process of rolling out a new look and feel across the app. The rollout is in progress and we will be finished in another week. I apologize if this has caused some confusion for you.
Thanks
Cheryl
