I had an encrypted note in Evernote where I kept my passwords. For a while, I was able to access this file normally in my desktop, and intermittently on my mobile phone (most of the time, nothing appeared, only the title). Today, I tried to access it on the desktop, and the encrypted file disappeared. The title of the note remains, so it wasn't deleted. Is it possible to restore the note to previous versions in an attempt to recover the file?
