I don't see how two different people could see them and on different devices if they didn't reach the server. I guess I will hope this was just a fluke. Thanks, Ron

The new edits don't show in the history, and the history doesn't have enough information (like who edited) to tell what happened. This case is not a huge problem, but if evernote is not reliable and loses stuff it is not useful.

I don't think so because it did not happen while editing. The additions disappeared the next day after all edits. Ron

I and my collaborator have both made extensive additions to a note but everything we added and both saw for at least hours afterwards has now disappeared and only the original note is on evernote. This is true across platforms (desktop, iphone, macos, windows) so is not a sync issue it seems.
