Airport ICAO identifer missing??

I’m am writing from the Lake Simcoe Regional Airport, located in Canada just north of Toronto. The airport’s ICAO identifier has been recently changed to CYLS, replacing the old identifier CNB9.

I noticed that FlightAware’s tracking program does not recognize our new identifier. It would be greatly appreciated if you could advise me as to how we can get this change reflected?

Thank you very much
