My due date was 25 Mar-2018 to submit schedule A and police certificates which is passed already. i uploaded my documents on 15-Mar-2018 and i submit yesterday (mean i complete procedure yesterday 16-Apr-2018) i submit again my documents through gckey account because there was a button like UPDATE INFORMATION and i upload my documents using it. now in Documents submitted by the client changed to replacement provided (before here was uploaded not submitted to IRCC) and View my submitted applications or profiles in column of detail before was YOUR ACTION IS REQUIRED and now changed to SUBMITTED. i am worried about the deadline because in instructions they wright that if you failed to send requested documents by due date, the status will change to overdue and your file consider to be incomplete and may be cause of rejection.
