Congrats! :)

May I ask when your tracker updated for the oath ceremony and when did you receive the formal invitation?
 
Yes that helps. Lawyers normally have 3 steps to approach IRCC. Each block cost 1-2k.
First they send a demand letter and the "Use of Representative" form. This normally makes IRCC move your file and do something about it
In two months if nothing specific happens on your file, you can file for the Writ of Mandamus.
If IRCC does not have a solid reason to fight, they will conclude your application before the court's date.
I recommend going forward with Mandamus. At least that makes this continuous pain to stop.
I just started the process. Stage one so far
 
My Tracker got updated for Citizenship Ceremony but no e mail/ formal invitation yet.
Congratulations !! you'll receive it in 24-48 hrs after the update. They say that if you do not receive the mail at least 48 hrs before the ceremony date, to call them.
 
I finally got my oath ceremony invite for May 24th! (Just after I spent a couple of grand on the writ). Ah well!
Congrats! :)

Ahhh, i understand...

i literally got DM the day after i paid $400 for an initial consultation with a lawyer hehe. But well, at least it's done for you! congrats
