IP2 , IP1 , NA .. all don't matter. Stick to the timeline and to the six months processing time. some applications jump these stages and some stay at one stage for most of the time and the randomly jump to approved without even noticing.
But if you need some comforting, this new methodology have been introduced beginning Jan1 this year ,as the biometric process have changed the way IRCC manage and run the application and hence everyone starts at IP2 ,even though the application didn't even start processing until applicants receive MEP and BIL and their biometric data have been uploaded to IRCC, then and only then actual processing starts and you are put back to IP1 and then NA then IP2 then NA again till you get PPR
