Google Calendar not working

[cesar12]

I have a new hire who cannot access google calendar, it is in a loop redirecting to verify its you and once I select continue it send me back to the same page. I attempted to delete cache, update chrome, use another device, use a mobile device (worked). Any suggestions?

Is Google Account profiles used to sign into the Chrome browser? If so make sure the same account is used in the Chrome browser and for the Google Classroom APP.  The avatars should be the same in both locations.
