Hi Shazahsan, can you see any changes to your account now? As I checked today and to my surprise now I don’t see my mailing address! Not the home country one or the one here. I tried to change to address again( just to see) if it shows any mailing address; and those fields are blank they don’t show anything for mailing address.
I changed my address using the online service the day after I received AOR/when was able to login to ECAS and mine still hasn't updated either. It's been over 2 weeks now. They say it should be updated in 5 business days, but when I submitted my address change online it says 15 days on the page after submission. Either way, it's past both those deadlines now, so I just sent them a webform with my updated address and am waiting for a response now.
