I also received a ghost update this morning. I logged in into my account and the status bar says "Profile/Application Updated" and it went back to "Submitted". This is my second ghost update but the Review of Additional Documents still says - We have received the additional documents you provided.I had ghost update. From submitted to application updated and back to submitted again. and thats it. No email or messages on my Gckey account
Not sure what's next to be honest.
