Only those applicants whose documents were pending to be reviewed by the officer is seeing the status of Not Applicable instead of We do not need additional documents. This is also an indication of the fact that this is not a technical glitch but the real-time status of the applicants' profiles.
Background:
Files were already being reviewed at Local Visa Offices and many pending documents were already reviewed by officers. However, due to system upgrading, it was not getting updated in your profiles.
Now the latest update from IRCC means all pending profiles are updated and we have seen massive IP2 yesterday with some applicants seeing Not Applicable Status in ADR section as well.
NA Impact:
In the past, I have seen a trend of applicants profile changing back to We do not need additional documents from Not Applicable few days before File is approved. However, there are also few cases where PPR was issued without any further change in accounts.
Conclusion:
If any applicants have a doubt on the status of their files that they can apply for GCMS Notes or email their Local Visa Offices to confirm the status of their files.
I hope this will help. Good Luck.
