Oh what update exactly ? I also received, but it was the status itself. It went from application approved to medicals approved and then back.
My old medicals expires on 19th June, so my counterfoil is still valid.
I saw "application/provide updated" on the home page on 13th June, but no change inside. I had some hope that it was about new medical. However, yesterday I got an email from IRCC asking to renew medicals.
So don't know what was updated or is it just a technical glitch.
