Statuses in myCIC mean nothing, it looks like they are random. Together with family, we landed on Oct 18. I already received mine PR card and two cards for my kids.
Status in our applications Review of additional documents: The additional documents you provided are being reviewed. Final decision - Application approved.
For my wife, there was nothing (status in her application Review of additional documents: We don't need additional documents) I waited until 61 days passed (December 18) and I contacted CIC. Lady told me that there is no note about photos or whatever. She told me that she will send an email inquiry to the visa office. Because I do not trust them I also send the inquiry via IRCC webForm (they have 10 business days to respond). On December 20 staus in my wife application changed to Review of additional documents: The additional documents you provided have been uploaded. So far it stays the same. We did not receive photo request or the info about the card.
I hope they sort it out for your wife pretty soon man!
