I have Evernote on a laptop, desktop, and Android phone. The desktop and Android are fine, but the laptop has started displaying a version of this symptom of blank notes, not blank on other devices or in preview. One of the suggestions I saw elsewhere on the forum was to do a sync, but if you see the images below, there is no sync button on the laptop. I have also noticed that the About, Check for Update, and Release Notes windows are also blank on the laptop. I think everything was normal Friday night, but then like this Saturday morning. The difference in screen layout is puzzling.
