I use both OneNote & SkyDrive applications. The OneNote updates initially synced with Skydrive. However, from last 5 days any update to the OneNote file is not making it up to Skydrive (Last Modified date is showing 5 day old date). I have attempted Sync from Desktop Onenote, and do not get any error messages, but the sync is not happening and the last modified date has not changed.
I am using a Droid phone where I have OneNote app as well. The Droid OneNote shows 5 day old notes. I don't update both OneNote Simultenously.
