Hey, Congratulations on your DM
I am May 8th applicant too. I got a ghost update as well yesterday but i know whats the update.
Additional document line changed from " We
received additional documents you sent" to "We are
reviewing additional documents you provided" I submitted additional document on OCT 20th.
Today i got a new line added in PA's ECAS " We started processing your application on NOV 25th 2019" -> Did you receives this sort of ECAS updated on your PA side ? if yes, whats the date mentioned ?
