I am seeing the same issue with a native iOS app using WeatherKit.framework. Runtime error: WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 I verified: WeatherKit is enabled for the App ID A new iOS App Development provisioning profile was created after enabling WeatherKit The app is manually signed with the new profile The app was deleted and freshly reinstalled on a physical iPhone The built app contains com.apple.developer.weatherkit = true The embedded provisioning profile also contains com.apple.developer.weatherkit Bundle ID and Team ID match the App ID The issue persists after waiting and rebooting the iPhone Bundle ID: de.praxishartlep.weathermat Application identifier: .de.praxishartlep.weathermat This looks like the same server-side JWT minting/authentication issue described above.
