If I register an Azure AD app using "App Registrations (preview)", I can't get it to work with Device Flow. If I use the older "App Registrations", it's fine.
I'm using MSAL .NET library, and device flow, and get this back from the server: AADSTS70002: The request body
must contain the following parameter: 'client_secret or client_assertion'. Only when using (preview), with all 4 suggested native redirects ticked
