Unable to block custom IOC URL indicator on Chrome Browsers

Hello, I created a custom URL/Domain indicator to "archive.org" to test the capability to block on Chrome browsers on our Windows machines, but this block only functions on Edge browsers and not Chrome. 

I enabled "Network Protection" on the configuration profile and the system I tested has this feature enabled successfully. 


I also enabled "Custom network indicators" prior to creating this "URL" block indicator. 


Can anyone please advise on what additional configurations are required for this feature to work? 

Do I need to have a "fully-managed" device enrolled to do this, or will URL blocks also work for partial-managed (BYOD) device enrollments? 

Any help is appreciated!

    Michael39, is your test device correctly onboarded to Microsoft 365 Defender for Endpoint? Is it visible under Assets -> Devices in the M365 Defender portal?

     

    Is Defender Active AV?

     

    Thank you
