I want to block SaaS apps using Microsoft Defender for business. I used tags, created a device group on Defender, and added 2 devices to it using tags. In Defender settings, I went to Advanced Features and enabled Microsoft Defender for Cloud Apps. I blocked WordReference(dot)com for testing purposes and applied the policy to the group I had created. However, even after 4 hours, the devices in this group can still access the website.
What configuration step am I missing? I am currently working on pre-test devices, which is why there are only two devices in the group.
