If your passport is already updated with spouse information, you do not need to submit the marriage certificate.
Otherwise they are asking for the marriage certificate.
How did you used old system to check the status.
I used several ways like UCI, citizenship application number etc. - Every time it was showing we do not have any application in progress.
We were not able to identify you using the information you provided. There could be three possible reasons...
It seems - in some cases local VO confirms the UP and most of the cases not.
You can see UP approved cases gets their test invite so quickly.
After test - DM, it takes a month to two (including Passport pages request). Compare the Excel-tracker 2020 and 2021 to get some idea.
it is my personal...
