For me, my Passport reached on 31st Jan and I got my 1st message from VFS ( invoice cum receipt) on 1st Feb 4:30 pm. And got tracking ID around 6pm same day and it was send to IRCC on 2nd feb. so I am assuming ,you also might get it today evening.
As far as I know , people who got their AOR since march 2020 are still waiting for their for their PPR , so I am
not sure what they meant by a week ..?

I have raised this issue in twitter and I just got this response for IRCC Twitter account
"Thanks for flagging this. We’re aware of this issue and working to resolve it. Thanks for your patience and sorry for the inconvenience."
In my opinion
In my opinion you don’t have to resubmit every time . I tried that till last Saturday it didn’t work .From what I can gather it looks like they might be admitting people In batches, so don’t worry yours also will be approved soon
