Problem with SSO with Azure AD

[Robert Stead]

Getting error below, tried to setup for the first time last night and I think I stuffed up something.

AADSTS700016: Application with identifier 'https://auth.atlassian.com/saml/21466960-f66a-48ab-8b65-59ba9dd03432' was not found in the directory '1b7e008e-8d66-427b-9e8a-a91aa2d75bcb'. This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You may have sent your authentication request to the wrong tenant.

I can't login to create a support ticket, anyone able to assist.

Thanks
