Yeah, exactly what happened to me. In the additional documents section, it changed from "We don't need.." to "we are reviewing" in couple of hours in the morning, now it's switched back to "We do not need...".hey Lucas, I have the exact same AOR date with the exact same status as yours (well, the only difference is that my security hasn't started yet). I just checked and found the same update. That is, my CIC account has also changed from Submitted to Application/Profile Updated. I also noticed that my "We are reviewing the additional documents you provided" has changed to "Not applicable". Not sure what that means..
Did you submit any additional docs via webform before that?
I did submit my spouse's documents, I believed they might review it this morning.
