No, you have to look for it in your online account.
The application status changes to "Application/Profile Updated" but when you open there's nothing changed and when you go back to home page it changes back to " Submitted". That's what a GU is.
When we create the profile in the pool we enter our TRF number that is good enough for them to validate the IELTS score. In case they are not able to verify they will send an ADR, so nothing to worry.
I totally agree with you, Keep opening the website like every hour just to see in case they open it up or provide any update as to when they'll be opening. Its really frustrating.
And I think these are unprecedented times and I don't think even IRCC can do anything about it. Still these guys are sending out invitations and processing files as quickly as they can, we should show little appreciation to that.
