Is it an email notification or you happen to check in the GCKey Account login? Once they start reviewing, I believe PPR will be within weeks. Good luck and keep us posted...I submitted PGP application in Oct 2021, and got an additional doc request on May 4th, 2022 and submitted the docs on the same day.
On August 16th, I got a notification from GCkey saying they started to review the additional documents I submitted.
