According to my experience and friends in here and facebook, it seems that once you application is approved, VO will issue the COPR first (which we don't know before because it won't show on the ecas or online account). After COPR issued, there will be someone prepare PPR letter to send to PA. So the new tracker portal actually helped!
Once eligibility assessment and background check completed, it should take one to two week to issue the COPR which will show on the new tracker, then one to two week for the PPR.
