Did the tracker at least update that you have completed the test? FWIW, I did send form out asking if there is any way to expedite the application as I was travelling internationally and did not wish to get oath date during my time away. Did get a response back asking why do you think that is urgent? As urgent is only if someone is dead or critically ill and you HAVE to visit them. Did not respond back to that request as that did not apply to me, but the request was sent on Dec 19. The response with the above message was Jan 20, and Jan 27 was my ghost update. So not sure if this was connected or not, but does not hurt to at least send an email asking for an update!
