HiDid you receive the “unable to verify your presence in Canada prior to your PR” ? If you did not it may just be the IRCC taking a long time to provide the AOR. It’s not unusual for the AOR to take 90 days. If you have heard from them and they have been unable to verify you time in Canada I would wait till you have sufficient days post PR date and resubmit since you are so close without the pre PR days.
I hope you are well.
I have the same problem now. I already sent an explanation letter and all proving documents.
Do you think I need to Contact MP on this regards? Do they really help?
