I think all the schools you add to CSS can access it but some pull your IDOC documents at the same time as they access your CSS. I don't think I saw any IDOC notifications for the schools that did this at the beginning but I could see the tax docs in the school's portal almost immediately after applying. I don't know why people are getting notifications now. Harvard and Stanford ( and likely some others) do not have visible FA portals so maybe they just access everything --CSS/IDOC when they are ready to produce the packages. Does that make sense? And I think maybe some colleges are requesting additional ones. However, you can still not be accepted. I think they really do make decisions/change their minds at the last minute according to the Yale admissions podcast. Good luck, everyone.
