Yes, my tracker showed updated on September 23 and I got P1 on September 18 (responded in exactly 30 mins, lol). I have a theory on a number of things that could cause it though. One of them would be the fact that I have a new residential address now and I put in a different email because I had created a Permanent Residence portal back when I was preparing for Non-EE PNP application, using the current email linked to my Express Entry application. So new house address and email in P1 response can warrant a profile update. Another could be because I recently requested for GCMS notes for the application and the tracker update was like a day after the GCMS notes request was submitted.
Everything shows completed on my tracker and I can see the COPR number already. No GU on GCKey either, last update was FD on September 15. My enquiries (call, email or webform) gets updated on my tracker too and I can see it in the notes as well, so I'm not bothered about the update. If anything, I feel its my ECOPR being updated and P2 on its way real soonnnn! Hopefully! Lol.
