In my case the new tracker says that my application was filed on April 13, 2021 and application was last updated on April 23, 2021, but this does not have the same previous In Process meaning. My status in the old ECAS is still showing as application received and that they sent the AOR, nothing about being In Process yet, that is why I haven't updated the spreadsheet. The spreadsheet will need to be updated to account for the changes in the new tracker, but I am not the admin, therefore I don't know if that will happen this year, in the meantime if we have access to the ECAS we will count on that information!!!!
