We turned on SAML for our account and it seems something is not working at the Atlassian end. After Okta authentication Okta is re-routing to Atlassian however Atlassian errors by giving the following error.
Whoops! The address you entered doesn't seem to be a valid email address. Try checking your email address with your organization admin."
I know i am typing in the right e-mail address.
Is there something Atlassian has to do to "move" Atlassian managed accounts to SAML ?
