From all evidence NDVO effectively stopped issuing visas including COPRs - and the VACs were closed as well - from the start of the direct flight ban. Even those who had outstanding PPRs or had submitted them already were just frozen.
Obviously since they weren't issuing visas and there was nowhere to submit passports, they also stopped issuing passport requests.
Not long ago they did re-open the VACs and start issuing visas and coprs again.
So now there is a big backlog. A very big backlog. And I presume there are still work restrictions and covid-related limitations, i.e. they are not up to full speed or staffing levels anyway.
Now if you follow the various indian threads, there is a fairly high pace of PPRs being issued (the thread on two way delivery for NDVO for example) and visas being returned, etc.
There is a backlog. It is going to take time to catch up.
