The review does not block the data being added, it's more of a request for feedback. Different maps have different update cycles. The slippy map on osm.org is meant to update as quickly as possible, usually a few minutes, but sometimes there are hiccups. Zoom levels that show larger areas also update a little slower. As long as what you are adding is up to date/accurate, I wouldn't worry about whether you've captured everything about the features. "This thing is here" is a lot better for the map than no information.
