It says on CIC website they update ECAS on a weekly basis, usually Tuesdays. It's been 2 weeks since address has disappeared, not back up yet.
ONE 2 KA 4 said:Same here, our files are in Q to review, until review is not done and updated, address will remain disappear.
One thing I noticed when address disappear they mostly dont reply to your email. Could be awaiting for new update before they respond.
