Web content filtering and indicator aren't working on third party browser

Still does not work for me either. I currently have a case open with Microsoft Premiere Support and its going around in circles. We have checked and rechecked the same configurations and despite everything the behavior remains the same - Edge consistently works, Chrome does not. This is very clearly a broken service and Microsoft on the hook to either fix it or formally declare that they don't support 3rd party browsers. I have sent Premiere Support a half dozen reddit and techcommunity posts highlighting this but we'll see if it reaches the right people.

In the meantime, I have applied a workaround in Intune using a device configuration for Chrome using the "Block access to a list of URLs (Device)" setting and adding the same list of URLs. It stinks that I have to maintain two lists and I don't always receive Defender alerts but at least its a consistent workaround since Chrome is the most popular browser in our small company.
