Pretty sure the “lite” version were just decluttered versions with features missing and better optimization (usually aimed at developing countries). They likely track as much (well, probably not as much because there’s no point in tracking stuff that the app doesn’t support).
I’ve actually noticed they started decluttering the messenger app. Rooms are gone and they’ve also removed the chat suggestion bubbles at the top. So when you launch the app you only see the conversations you have active.
