There won't be any ghost email. And you guys would already have that update but you didn't notice. If you open your Express entry account it'll show application updated, however nothings chnaged whatsoever. That's called ghost update. But it won't last for long. So even if yoh had it, you didn't check your account during that time and you missed it. But if it's says "make sure to check messages " on top then it means your file has already passed few steps.. and it's in almost last stage.
