6 months is process timeline as per IRCC, so 2 months in IP1 seems pretty normal. Don't get restless looking at successful applicants here. For every 1 PPR granted for June applicants, there are roughly 9 applications which are still pending (May submissions have ratio of 1:4; both based on sample in immi-tracker). So, you are in majority of the cases (perhaps unfortunately in this case).
You can ring IRCC. They don't talk in terms of IP1, IP2 etc but will let you know a bit more detail about the status - like visa office, eligibility met/passed, criminality and BG check started or not etc. Hope this helps.
