For you, is it just "Processing >> In progress"? I thought you previously had N/A.. to know whether its IP1 or IP2, need to know BGC status changes from start. For me, it was like "Processing >> Not Applicable >> Processing" and then "ADR >> PAL >> DM"
Here is the flow from my timeline:
Right after getting AoR email, upon linking the application (to GCKEY), I saw that BGC indicated "We are processing your background check." So this might be FALSE IP2.
Real IP1 - I never saw my Background Check in "Your application is in progress". I used to login to check GCKEY everyday, 2~3 times a day (even on weekends). I might have skipped IP1 maybe coz I'm inland perhaps?? I may be some of those applicants who skip this stage.
NA2 - My BGC went "Not Application" - no email or GU. Some folks say its glitch and what not (as per IRCC call agent bla bla) - I don't believe it nor think it to be glitch. I think BG check when NA is like either IRCC waiting on CSIS & CBSA or both Or that info from both CSIS & CBSA has been received for applicant, VO is to further update application. or that I could be wrong, but "N/A" is certainly not glitch per say.. I was looking at very old post, like from 2018 and before, N/A means something something, everyone has their own version of story, some got GCMS notes before or just after this phase, and so they have their own say.
Real IP2 - Up logging into GCKEY, I noticed GU, "application/profile updated", BGC change to "We are processing your background check." (from N/A).
