Mine has been in "we are processing your background check............." right from the moment of my AOR on 4th Oct, I do check my account every day and never saw it change. However I called an IRCC agent on the 31st Dec 2020, I was told eligibility passed, criminality passed, security in process, the agent went further to say that he doesn't know how long it's going to take to be in process, but security could take from 1 week to several months.
So I don't think all applications would have those changes on background check reflected on their accounts.
