Whenever I create a new folder on my computer at one location, it uploads fine and I can see it on Box.com. When I get to my other location, the folder is not automatically synced (although the Box Sync app says "synced"). I can go to the website, click on the folder, and tell it to sync manually - at which point my second computer downloads it as expected. Having to do this manually kind of defeats the purpose of Sync though, and it has happened 4-5 times over the last few months. I don't recall if there has been a folder that *has* synced correctly in that time. I am the only user and I am just syncing folders between two computers.
