Users unable to login into Azure Devops after connecting to Azure AD

Issue:  Users unable to login into Azure DevOps after connecting to Azure Active Directory

Solution: Sometimes some users might not able to login into Azure Active Directory. This is because the users might not be part of the Azure Active Directory.

To make sure that’s the issue, login into Azure DevOps & then Disconnect from Azure DevOps if you are one of the Org Administrators and then again ask the users to login. If the users are able to login then that’s the issue. After that again connect the Azure DevOps to Azure Active Directory

Then solution is ask your Administrator to add users to Azure Active Directory.
