Hey ! Granting screentime authorization doesn't work on the simulator, only on real devices. You cannot really test the screentime apis on a simulator, but you can add #if targetEnvironment(simulator) checks if you need to other parts of your app.

We experience the same issue on our app, and we filled a bug report as well -> FB12235755. The issue seems to happen when screentime permission have been granted prior to iOS 17. In our testing, everything based on DeviceActivityReport fails to render until you reinstall the app. here's what we see in the logs: Failed to discover the client's extension: Error Domain=DeviceActivityReportService.ReportViewController.ClientError Code=2 "(null)" VS terminated with error: Error Domain=_UIViewServiceErrorDomain Code=1 "(null)" UserInfo={Terminated=disconnect method} I agree this is a big concern for us as well, we don't want to ask all of our users to reinstall the app after updating to iOS 17. This is also showing how little control we have on DeviceActivityReport views, we cannot know if they are loading, if they errored with the public API, we opened a enhancement radar on this about a year ago (FB10754858).

yay the limit is 49 domains / 49 apps, if you cross it, it just stops blocking. This limit is not documented. We reported the issue in June last year -> FB10511690. Can you do the same to help getting this issue fixed ?

Definitely working for us with the individual permission ! did you try to repro your issue in a sample project ?

Hey ! We experience the same issue, we created an improvement bug report for it, you could do the same to increase chances it's being looked at : FB10754858 -> Provide a way to monitor data loading / error states on DeviceActivityReportScene

Honestly I'm using the same method you mentioned to stay up to date, also taking a look at API diffs when new sdk versions are published, and testing beta iOS versions as well when they go out.

Hey ! Our users report similar issues, it's even happening on different categories like "Productivity and Finance", or with particular search in the picker. We opened a bug report for it in august, If you could do the same it would probably help to get more visibility on if from Apple ! You can reference the FB11400221 bug report ID. 100 % agree that the picker in the screentime settings is better ! Don't know if you noticed but the developer accessible one got a search bar since iOS 16.4, and we got several radar fixed as well, so things are moving !
