Their AOR is kinda like spouses second AOR, it takes a bit after applying and after it’s received it’s very quick. You can check that several that was approved in 2 weeks after AOR got the AOR a while after applying.I don't have any statistics to back my claim but I don't think TR to PR is an issue.when ever I open fb my feed is flooded with TR to PR "finally I recieved PR blahs blahs blah....." and I have seen most aproved in a week or 2 after AOR .So that doesnot seem like an issue.(conditions apply-we are dealing with IRCC)
