Oh, I did then. I already got the citizenship though in August (roughly three months after applying).

Hi can you please tell me one thing
Did you just attached a seprate document and explain on that or just filled in that webform box and explain there ?
 
I just got the automated response for the web form submission and they never replied back. However my BG and test are both completed now so I guess my application is being processed normally.
I am in same boat I have missed updating one old immigration status. Can you please let me know did you face any issues such as delays etc. in application process because of this ? I am submitting the webform to rectify this mistake.
