Good to know, thanks. Will encrypted notes sync betweeen devices?
I doubt it. All the newer features (those introduced in iOS 9 like formatting) only work for notes stored in iCloud. The IMAP stuff seems to be deprecated/in transition.
Not anymore, in the last release thry switched to iCloud syncing.
IMAP is still supported.
But not for notes with the newer iOS 9 features like attachments.
iOS Notes syncs with Exchange and IMAP at a minimum. I'm not sure if the updated features work outside the native Notes storage though.
Would a) love to know the answer to this and b) if not, would love to see this happen.
