HiDid you update your "email address" or mailing address or home address?
If you have a new email address, you need to call. IRCC will send AOR with application number to your email (when the application was submitted). You need AOR to begin to link to your account to track progress.
Before the account is linked, email is the main communication form.
If you only change the address when you live, they don't usually mail snail mail to it. You can update your address in web form.
Home address and mailing address are same for me.
I recently move to diff address.
