Hello -
I noticed the same status on my profile today... (I think the actual update might have happened a few days back because I have not checked my profile since last 3 - 4 days and today is Sunday)
Background:
AOR: May 6, 2017.
I missed the US PCC for my spouse when submitting the profile initially., CIC asked for that missing document on July 12 and I provided that right away.
Since then I have been seeing the following in application status.

Based on the comments on this thread it seems that nobody really knows what does that mean..but if someone knows.. please share or provide an update for their case whenever they have an update.
