Not to disappoint anyone, but sometimes a "ghost update" can be triggered by yourself because of a glitch in the system, in other words, make the "Current Status" show as "Application/profile updated".
If you click on "Check full applications status" and it takes some time to load, and you decide to refresh "List of applications page", it will most likely and momentarily show "Application/profile updated", even though nothing has changed.
My anxiety developed by IRCC has tricked me so many times that I've learned that a few months ago.
