For Adobe employees I logged in to the app with just my user name (no "@adobe.com"). However, when clicking on "Feedback" above, I get an error that I can't be logged in. I then had to add "@adobe.com" and use my forum password to login to leave this feedback.
If I relogin into the app, the same problem happens again - ie, it doesn't remember my login for the forums, just the one for the app.
