Admin quarantine option is unavailable for malware detected files in MDCA

Howdy! MDCA Brain Trust,

I've configured Admin Quarantine location as per the following Microsoft guidance. Created a brand new SPO site and assigned it in the setting. It's been about 3 days (waited before I post this here as it may take a while to reflect the change). 

https://learn.microsoft.com/en-us/defender-cloud-apps/use-case-admin-quarantine 

Admin quarantine option however, is still not available for Files detected by MDCA as malicious. Ideally, I should be able to Admin quarantine OneDrive, SPO files detected as malware. 

I can however, see the Admin Quarantine option in the governance actions in policies but, this isn't the option we're after. 

Also, Microsoft says MDCA will provision a new folder (See below) in the site which I don't see either. 

Has anyone experienced/worked around this issue? Appreciate any suggestions to sort this out!

Thank you!

Manoj
