I think you should contact them now if you have not done so already both by phone and by web form, a colleague of mine with very similar timeline as yours and they already got their passport amidst pandemic.August 2019 i sent my application
Within a month probably september 2019 igot my AOR
Jan 2020 i had my test
and then nothing while the officer at interview told me ull get ur oath in 3 months and till now nothing ,instead they put me in non routine
I ordered my GCMS notes 4th time. No movement . Just says Location :Box Transfer cen , i dont know what that means.
More often than not non-routine happens if there was an issue in your background check (whether its a genuine issue or not), amongst other things.I believe background checks happen after test and between oath so this could be a possibility. I know someone who faced a similar issue due to their name. I wont get into any further detail but these things happen.
You might also want to contact your local MP’s office for assistance. Recently I got a flyer from my local MP and citizenship assistance was one of the things mentioned in the list of services they assist with. Good luck!
