How do I change the note thumbnail to show the first page?

Android 

Open the app settings, tap on Note editor, then check Display first page as thumbnail.

With this setting enabled the first page of a note, such as the cover of a book or a title page, will always be shown as the note's thumbnail image, regardless of the last page visited.

Windows/Windows Phone

The last page visited in a note is always shown as the note's thumbnail image.
