It's a complete mess up. I get it every application is different so processing time can vary but they can atleast open the packages in chronological order. the process to AOR remains same for everyone. I know people waiting from June with no clue and many of the December folks getting temporary numbers and confirmations from IRCC that their file has been scanned. They just don't care
This is my issue with IRCC the Receipt to AOR. Beyond this I know it's case by case. But, people would not feel discriminated if things were initially being handled in some kind of organized fashion.
