HORRIBLE EXPERIENCE. I was offered a free 30 day trial. Did not like the app & tried to cancel immediately problem was NO OPTION TO UNSUBSCRIBE. I contacted Dropbox a total waste of time. They send instructions that again have NO OPTION to unsubscribe. I called ITunes followed their instructions, And NO OPTION TO UNSUBSCRIBE. I've been trying for a month now... STAY FAR FAR AWAY from this app!
