IRCC is very disorganized it takes weeks and sometimes many months to acknowledge, and sometimes they won't acknowledge at all. it is painful, you have no other option other than calling and checkingSame here! I have submitted document through Webform on June 4, 2024 and have not yet received a confirmation email. Since then I have called IRCC and they do not see the document on my application. Resubmitted document through webform and it is all the same. Any suggestions on next steps?
