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).
