Hi All,
Just for your records, My wife and I got our Citizenship status changed to "Completed" exactly 5 weeks after I took the test and more than 3 weeks after she took the test (both got updated at the same time).
FYI, the photo I took from my ID definitely was blurry for some parts but apparently it didn't end up with any issues. My wife also made a mistake first time and took a photo of herself instead of her ID which ended up with receiving another link a few second after to do the test process again.
