Honestly I wouldn't worry about it. Those dates are wildly off and never updated on time. Just track your case by the case numbers and be patient. For my case, I didn't hear anything other than my case was received, my EAD had shipped and then 6 months later that my case had been scheduled.

But if you still want to look, look up your field office. Not the National Benefits Center. They can take however long before they sent it to where your interview will be.
