It is reporting canvas. You will need to go into your admin layout template and add the reporting beta to your main menu. Then (if they have reopened the Beta), you can opt in and Adobe will copy your data over for the Beta. Ours took about a week to get activated for testing.
That being said, remember, it is in beta. All funcionality is not present or may not work as expected, but that is the nature of beta releases.
If you encounter issues, it is good to document what you were doing when the problem occurred, and how to reproduce the problem. This will help the developers to diagnose and fix problems.
