Hi
On Tuesday (day of approval) the status changed to decision made, and it had approved under at the bottom. But it didn't have any alerts or notifications.
The next day I received an email saying there is a message for me in the CIC account, and once I logged in there was a message that said it has been approved and will be posted to me at the address provided on the application.
I do recall that when I initially linked the application it gave me message saying that I will no longer receive messages via email now that it has been linked, so I'm not sure if that means you will receive the updates via email if you haven't been able to link it.
