I have a Windows 10 UWP app that uses roaming settings to store user settings. If a user installs the app on another Windows 10 machine, her settings will follow her there. Great!
I want to publish the app to Xbox One, but seems roaming settings are not supported: UWP features not yet supported on Xbox
Roaming settings are not synchronized on Xbox. The roaming setting APIs may be called, but settings will not be synchronized between devices.
How can I achieve this on Xbox?
The document clearly states that RoamingSettings is not support synchronized, so there is currently no other way to call it.
You can explicitly remind users that the synchronization of roaming settings between Windows 10 devices and Xbox is not supported.
If you want to synchronize user settings, you can consider building your own server, save the user settings in the server (such as create a database to save the data), and synchronize them when the application is started.
