FYI, the exact same thing happened to me. To fix, I did the following: - uninstalled Evernote, - renamed the Evernote directory Evernote_bak - installed the latest Beta - let the client re-download all the data I have two PCs at work, one with the latest official release, and one with the latest beta. At home I always have the latest beta, so this morning some of the notes I put in last night from home did not show up on my work installation because of the sync issues that apparently I did not notice. Can you please make the notification popup for sync issues red or something like that
