I have found that Ubuntu One sometimes will sync a local file to the Ubuntu One website, and other times it will not.
How can I debug this?
I'm sitting at my machine making edits and saving several files, all of which are in folders that are to be Ubuntu-One sync'd. When I look at the website (even much later, say, the next day) only some of the files were sync'd.
EDIT 1: I'll add this: I only see this problem with folders other than the Ubuntu One folder. The Ubuntu One folder seems to always stay in sync.
