Yes, it seems to be a monthly pull from the database. Sometimes things get reflected the next day similar to eCAS. For example, if you call IRCC, you will see an enquiry show up the next day etc. Check it tomorrow along with eCAS.I’ve got the tracker. From my experience with it, it does not accurately reflect the application status. When I received PAL, it never got updated until April 19 (when almost every application got a strange update). In my opinion I prefer GCkey to the tracker, though I occasionally check the tracker.
