One Note Sync Problem.

I have just realised that OneNote the Free Windows 10 App  will sync with an iPad App of OneNote .
You can only create encrypted pages through an Apple App using OneNote on the iPad.
You will need a log in to One Note if you use Windows 10  but avoid the trap of also clicking ypu want to log in with a Microsoft Account . Just Log In on the App and skip the Windows log in option.
It will work and Sync if you log in as a Local Account on a PC as long as you then log in on the app.
do not select switch to Microsoft Accont  log in on windows start up
You do still need to be signed in to the App to use it.
