same here.. even mine hasnt updated.. but one of my friend who appied on 18 july has got his medicals approved on Sep18
There is no particular templet in updating abt applications by IRCC nowadays. Anything can happen at any given time. That’s it
 
Same situation as mine. I got my upfront medical after I lodge (July 20). I received a medical request last Sept 18 and send my e.medical last Sept 20 through webform. But until now I don't receive any update in my GCkey account. I am worried because they only gave me 30days to secure my medical (as shown in the letter request).
