I had 1/2 doz. pages of notes and after several weeks most of the pages just disappeared. And now when I write a note it disappears as soon as I change apps. I cannot get the ipad to save any notes. Also, my manual says to click on notes in the settings, then on "accounts." But there is no "accounts" only a choice of fonts. How do I get it to save notes and are my old notes permanently lost?
