As soon as I learned that individuals who submitted their applications after June 14, 2023, need to provide biometrics again, regardless of their validity, I promptly paid for biometrics and uploaded them via webform even before receiving my AOR. While some suggested waiting, others were facing delays when asked to pay for it. Moreover, I received the request for biometrics within a week after my AOR. Therefore, my suggestion would be to follow IRCC's guidelines and proceed with the payment as soon as possible.
