If you message them, they send you a copy paste respond that they have received a large number of requests and cannot process requests in a timely manner.
But, I haven't seen anyone being able to get a response from them since Nov 2024. I am also waiting on my request since Nov. I think they stopped responding to immigration related note requests. Probably since they are understaffed and a lot of applications are sent to CSIS for comprehensive screening.
You can file a complaint since they are supposed to respond within 30 days, but that doesn't go anywhere.
