In Reply to RobinRobin, EN support confirmed the facts of my original post. That was a while ago, not sure if anything has changed substantially. My solution was to change how I use EN. Most of the notes I need on my mobile devices are trivial things like grocery lists, movie watch lists, etc. More serious/critical notes are being maintained in OneNote and NoteZilla on my desktop. So with the way I'm using EN now I might not even bother to restore it if something went terribly wrong, I might just start it over again because the material is not important compared to what is in the other apps.
