Leaving this here for the next person who needs help: lets say you have this in your context: extension DeviceActivityReport.Context {     // If your app initializes a DeviceActivityReport with this context, then the system will use     // your extension's corresponding DeviceActivityReportScene to render the contents of the     // report.     static let totalActivity = Self("totalActivity") } You have to put this in your actual app AND in your DeviceActivityReport extension.

I am dealing with this in January of 2023. Any help would be appreciated!
