Had this happen to me last night.
45 minutes of work was not saved to my Ipad (had internet, but even if I hadn't, it should have been saved to the local device. Nope). I hadn't stopped working, or closed the app, etc. I had worked continuous for 4 hours, but the last 45 minutes didn't save. This is with premium, and the work was not in the note revision history.
I've been thinking of jumping ship to OneNote, now after reading how this is happening to other people regularly, goodbye Evernote. Sad, because I've used this app for almost a decade.
