Wait for IRCC to issue you the biometrics letter for your PR application. This is normal.Same here, I got the email as well that my payment for Biometrics is received. At this point we can only wait, earlier people were getting Biometric payment letter just before 90 days after submitting their profile. Even though we received the payment email early but looks like it will take same time for us to get the Biometric letter i.e. around 90 days.
