But here is the thing that I observed. Not everyone got the update. It could be a ghost update. Looks like some files were opened and worked upon. Because when the October 7, 2022 update came into limelight, it was observed that each and every applicant got the last updated changed to October 7, 2022. Also when the recent glitch came few days ago, people complained that sections which were already "completed" reverted to "in progress", but the last updated date was unchanged.
Also I read somewhere (correct me if I am wrong), only test and oath are under the control of local processing office. On the other hand, background check, prohibitions, physical presence and language are supervised and managed by Sydney, Nova Scotia.
