I confirmed this with IRCC, they said processing time is not locked at the time when you initially submitted your application. In other words, November 2024 applications are still susceptible to the new processing time, i.e., 36 months at the moment. If in the next few months, the processing time increased further, let’s say 50 months, then it’s a 50 months wait time.
And yea, I agree that doesn’t make any sense, but .. it is what it is
