It varies greatly. Some people have been sitting in the "medicals passed" phase since October 2019 with seemingly no further status updates. Some people have had a "standard" (pre-COVID) 6-month processing timeline to get PPR. And then some people have received their PPR within 2-3 months of getting their ITA.
None of us know how IRCC decides to process all these applications, and if anyone is getting preference. Also, visa offices around the world are in different states of being open. Unfortunately nothing is clear at present for timelines.
