If it’s something recently added, the map can take some time to be rendered at each level. Usually within a few days your edits will show up at every level. It’s not that the data isn’t there, just that the tile server hasn’t caught up yet.

Thanks for all the suggestions! I have Go Map!!, but as powerful as it is, I really was hoping for something a little simpler for on the go walking. I’ve tried to find and download OsmPad, but it doesn’t appear to be available anymore (please provide a link if I’m wrong).
