Related to the above, I did some digging around my TY accounts, and noticed that the 'profile' seems completely separate from my CC accounts that the TY account is associated with.

Is there any reason for this?

Like, I've updated my address to my new apartment several months ago on my Citi cards. However, on my TY account, it still had the old address on the profile. You'd think they'd be the same! On UR and MR, it seems like those profiles are all driven off of the CC account..why does Citi make it silly like this?!
