Why does a document wait in Galley?

The first time Masthead sends each document, Galley keeps it in its Inbox, marked "From Masthead", until someone on your team files it in the data room (or deletes it). So you decide what goes in, and where.

When you file it, tick Keep this updated. Masthead's later versions then go straight into the same place as new versions of that document, so the link investors already have keeps working. Without the tick, each new version waits in the Inbox too.
