Exactly, that's what's worrying me. Even though you are a PR already, your tracker is updating. Mine hasnt. Or maybe I am just mindlessly worrying.. The eligibility has not started while the background verification is in progress. Any idea what does this mean?
I'd not worry about the date update or lack of tbh. What matters is that your application is getting processed. Since you are ~ 2 months into your application, nothing should scare you at this point.
It is very hard for IRCC to reject candidates unless a candidate has messed up(beyond MEP/BIL). If you reported everything right and have no background check concerns, trust me, IRCC won't do anything that should trouble you. It is one of the most fair and transparent immigration systems out there. I know a lot of folks here feel otherwise, but they should see what happens with other countries like US where genuine applicants can be banned for life from entering in the US simply because the officer ended up fighting with their spouse before leaving home.
As long as they are processing your application, you should be fine. They can take a break between sub-stages(e.g. passed criminality, info sharing not started) which can be annoying, but it is okay.
