So I have registered a new multi-tenant AAD application but trying to log in using the same account I created it with gives me the error
MSAL.Desktop.4.5.0.0.MsalServiceException:
ErrorCode: invalid_client
Microsoft.Identity.Client.MsalServiceException:
AADSTS650051: "Using application 'TestApplication' is currently not supported for your organization sample-company.ch because it is in an unmanaged state. An administrator needs to claim ownership of the company by DNS validation of sample-company.ch before the application TestApplication can be provisioned."
The domain name in question is already verified, so im not sure whats wrong here. After registering the app I just followed their Windows Desktop App Quickstart Guide and tried logging in with their sample project https://github.com/Azure-Samples/active-directory-dotnet-desktop-msgraph-v2/
Any help would be appreciated
