There is not set timeline, I have seen people getting ppr just the day after DM or even same day and I have also seen people waiting for one month to get ppr after DM. I have no idea how does this work? On another note, Congratulations, you are very close and it could be anytime soon. As for the ppr, sometimes it may go to your representative and sometimes they send directly to the applicant. So just keep your eyes open for your own email and keep following up with your representative as well. Good Luck and hope you get ppr soon!
