I landed on 8 March. I checked my account on Sunday and I could swear that the Status had something else there. When I opened it, everything was the same with no new messages. So finally sent them a message through the web form the same day asking if everything was ok since I had not received any updates despite linking my application to my CIC account.
A few minutes ago, I finally get the "We updated your application status" email and upon checking my account, I finally see an update on them having mailed my PR card! So happy to get finally get the update. I was beginning to get slightly worried.
