It is pretty useless actually as that is all on their website and they barely give any useful reply. But here is what the agent emailed me:
Good day,

Not yet. Patiently waiting
Still some way to go for 6 months benchmark. Although it seems they have quite some backlogs lately.
The 6 months deadline won't hold anymore if that's the case...
My profile has been approved on 8 Jan (CIC call) and still no PPR email, 50 days are left at my profile and my Medical will ends at 1-Sep-2019
Now I got amazing flight offer that will save for me about 1200$ US dollars from my home country to Canada, that flight date is 15-June-2019. Unfortunately it's none refundable. Do you believe that my PPR email can be late till that time?! is it risky to book it?
You should receive PPR in mid-March, so you should be fine with making travel plans for June, especially considering your application is already approved...
