Connecting data from Microsoft 365 Defender to Microsoft Sentinel

Clive_Watson - Don't suppose you are aware of any issues with the Microsoft Defender connector in Sentinel are you? It's worked fine for me since preview but now I get the following error on MDE and M365 Defender connector.

I came across the following article which suggests its somethign to do with the classic CA policy created when Intune is connected to Defender portal: https://www.lieben.nu/liebensraum/2020/06/aadsts50131-device-is-not-in-required-device-state-known-or-the-request-was-blocked-due-to-suspicious-activity-access-policy-or-security-policy-decisions-with-wdatp/#:~:text=If%20you%E2%80%99re%20trying%20to%20use%20the%20Windows%20Defender,see%20if%20you%E2%80%99re%20being%20blocked%20by%20conditional%20access. - I've seen another MSFT doc suggesting you should NOT delete this policy but instead you can exclude users, any thoughts?
