I posted my timeline a few pages ago, you can check. Ghost update wise not that I was aware of, as it was fairly quickly. My med approval was Nov 22, and afterwards the first email received was portal 1, which was Dec 8. Hope this helps.
I might have the latest submission date here:
CEC inland single applicant
AOR - Oct 18
First email for Bio update - Nov 20 (old finger print)
Medical Passed - Nov 22
