Intune Website Block Policy Not Working on Newly Enrolled Devices

We configured URL blocking for multiple cloud storage services via Microsoft 365 Defender portal at
https://security.microsoft.com > Settings > Endpoints > Indicators.

The policy works on older devices, but we recently discovered that newly enrolled Windows devices can still access those URLs — even though they show as compliant in Microsoft Defender for Endpoint.

Has anyone encountered this issue before?

    Few things to check:
    1. What is the organizational scope under the IOCs -- all devices or specific machine groups.

    2. The newly enrolled devices in MDE -> Device inventory shows as "Managed by: MDE" ?
