This is the normal behavior. The MS Sharepoint API's don't provide the Public URL. That URL is different than the actual URL of a document. It has a temporary token attached to it and is currently ONLY available through UI and not through APIs. Please note that there's no public link available and only private link in OneDrive (O365). OneDrive never had a public link available. OneDrive's API doesn't provide a Public URL when a doc is public. We only get a standard url to the document which requires Logging in. So even if the doc is public, you'd still need to login since the URL won't be public.
