I have not received AIP. I believe the reason is that I submitted my biometrics right around the next week to when IRCC announced the new two stage process.
I haven't filed for anything. I still have about 4 months but I am not planning to change status or extend my stay any further. I am hoping to hear back from IRCC soon since its high time now.
I saw quite a few people who applied in May sharing their good news about getting approvals. I don't know if any one of them have applied from the US. someone even said that they got approved without biometrics.
I applied in May as well but havent heard back yet...
