Hey there!
If your medical is not updating on gc key after upfront medical SDS, Don't worry at all
It was same for me and everything got updated the same day i got PPR, i was checking everyday 2-3 times a day and now it feels all that energy i was wasting by stressing over some stuff updating on portal was useless lol
just wait for the main email from ircc regarding status updating in your gc key and thats it
My timeline
Applied - 7th June
Biometrics - 12th June, updated after 1 hour of my appointment
No updates for next 2 weeks or so
And then PPR - 27th June, medical updated same day.
Passport submission - 2nd July in person.
Still at the ircc office under process
