I see "Domain Not Allowed" This usually means your email domain hasn't been whitelisted for your workspace. Contact your IT admin, or reach out to us at [email protected] and we'll help sort it out.
The Google or Microsoft button isn't showing Your browser might be blocking third-party cookies. Try opening Fibr in an incognito or private window, or clear your browser cookies and refresh the page.
