All 4 of them defaults to "In progress" in the tracker at the beginning. Test and oath remains at "Not started". Check
here in ECAS to know the status of when your file is in process. Since you got the AoR yesterday you should see "Application Received" and when you click, there should be line, 1. We received your application......
Line 2. adds when your application changes to "in process" from "Application Received" in ECAS.
ECAS and citizenship tracker are different. tracker was deployed very recently. Hope it helps!
