I created my Device Activity Monitor extension, and then attempted to start monitoring using the code example from the video: let schedule = DeviceActivitySchedule( intervalStart: DateComponents(hour: 0, minute: 0), intervalEnd: DateComponents(hour: 23, minute: 59), repeats: true ) let center = DeviceActivityCenter() do { try center.startMonitoring(.daily, during: schedule) } catch { print(error) } The startMonitoring call always fails for me with the same error: [monitor] Failed to create UsageTrackingAgent proxy: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service on pid 0 named com.apple.UsageTrackingAgent was invalidated." UserInfo={NSDebugDescription=The connection to service on pid 0 named com.apple.UsageTrackingAgent was invalidated.} Setting up the extension is a very manual process, so I likely missed a step somewhere, but any ideas on what this error might be indicating?

I see no immediately obvious technical reason why this should not be the case, but the patent for the tech does not describe being used in this way: See here: https://patents.justia.com/patent/11005986 Even more, there are some beautiful things that can be built with this one change. Pls Apple!
