Yep got the exact same two emails! I replied to both just to be on the safe side, and I'm waiting for my credentials. My GCKey hasn't updated apart from saying medical passed and I got my pre-arrival letter, but my ecas says decision made.Hey!
I got two emails ( one yesterday, one today) asking to confirm my email adress and name-UCI-email-first date of entry- last date of entry+where.
They weren't exactly the same but were asking the same info. Did you get the same ?
I still don't have any update on my GCKey, still says that they are processing, what about you?
Let me know when you hear something back
