Also not working on macOS 27.3 Developer Beta 1 (26C5035r).

With macOS 27.2 stable (26B123), the issue continues to occur.

I'm a user of said product and sitll cannot get the URL filter to function, due to serverSetupIncomplete. GitHub issues created on apple/pir-service-example as well as on AdguardTeam/AdGuardMiniForMac. Any help with this would be appreciated.

It looks like as of right now, the warning has been removed.
