Yes, we see it on our end as well.
In particular, when applicants receive, for example, procedural fairness letters from IRCC asking them to explain a discrepancy between the new application and the old application, IRCC does not provide a copy of the old application. It falls to the applicant to make an ATIP request for their old application, and then to continually seek extensions to respond to IRCC's letter by saying, “I have not received my ATIP request. I cannot respond to your letter right now.”
