It’s called ghost update. Maybe yes, maybe no! I mean, Not necessarily. Sometimes officer does something with your application, verifies something, or puts an important note, but nothing is changed in the tracker, because nothing is completed yet, or no document is needed. For instance, my application was updated almost 2 months ago, a few days after the FP request was sent to me, and no new update showed up in the system since then. Did officer do something in my application? Yes! Did I see any change in the tracker? No. Good luck!
