I feel you should keep checking your profile, it might change any moment.
I got a similar CSE email yesterday evening and now I noticed my Application is saying "Updated" instead of submitted.
On checking the application I noticed two changes:
The review of additional documents stated: The additional documents provided has been uploaded, then later changed to "the additional documents provided are being reviewed"
Also,
My BG has been on NA since AOR, has now changed to " We are processing your background check,we will send you a message if ..........."
Looks like you might move straight from IP2 to PPR in the next few days. So cheer up
