Missing App Engine Studio (AES) in PDI

[Dima1]

Hello, I'm a developer in training and I'm unable to find the App Engine Studio (AES) in my PDI. I am attempting the exercise from the first training module "Build an Application in App Engine Studio" but AES appears to be missing. I confirmed my user role is "App Engine Studio Creator" according to the instructions and I've refreshed my PDI but AES appears unavailable. The following page loads when I click on "Start Building", and searching the navigator for App or App Engine is not showing desired results.  

Any suggestions are appreciated, thank you.

I was finally able to get a Washington release PDI. App Engine Studio isn't showing in the available plugins, but is pre-installed... Planning to run an in-place upgrade to Xanadu so I'm up to date with AES. Wish me luck. 😛
