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

Hi Louis, Yes, I'm sure that all settings are correct. (Enabled content filtering policy and network protection). The feature was working fine before upgrading to 4.18.23050.3, and once we have rolled back to the previous version (by using mpcmdrun /revertplatform), the WCF and indicator will be working again. A Microsoft support guy has re-produced and confirmed that issue from his testing environment as well. I'm looking for a hotfix or mitigation to this issue but I haven't found it. All our endpoints have been impacted now even we have set the defender upgrade channel to broad channel to them.
