Hi, I've been cheerfully mailing files to dropbox for weeks and suddenly they are not being received. Typically they show up in Apps>Attachments, but lately...nothing. I've tried a couple of different ways to email tests in case it was an issue with the outgoing program and still nothing I haven't reached my storage limit, and have received no notifications of a problem. Not sure what to do to fix it. Problem began 3-4 days ago. Any ideas? Thanks!
