issue with [tenant].ciamlogin.com in authConfig.js

Recently, the domain ciamlogin.com was flagged by multiple sites and propagated into chrome and safari on iphone showing red screen as attached. My company Cisco Umbrella shows it as phishing site. I can't proceed with using my trial tenant or this sample. Any information would be appreciated. I've submitted an Azure Q&A in the Community yesterday. No reply yet.
