I keep reminding myself that citizenship grant is probably very low priority for IRCC. To be fair, at least for most applicants, whether you get citizenship or not probably won't impact your life much in Canada since you are already a PR. Even if you need to travel, you can always use your current passport and apply for visas as needed. The stakes are simply way higher for many temporary residents trying to get their PR applications processed.
I would love to get my citizenship sooner than later, but as long as I get it within the official processing time, I would consider IRCC to have done their job properly.
My AOR came from Sydney and test invite from Scarborough. That's all I know; I wouldn't be surprised if it has since been assigned to Vancouver since it's moving
