Other features or issues related to Microsoft Partner Center
Currently, the Universal Windows Platform (UWP) is no longer under active development, and new UWP-based games are not accepted in the Xbox Store. For game submissions to the Xbox Store, you might want to consider using the Microsoft Game Development Kit (GDK). The GDK provides access to the full feature sets of Xbox Live and the Xbox Development Kit (XDK), which includes capabilities like online multiplayer and achievements. This would be a suitable alternative for developing and publishing games on Xbox.
If you are part of the Xbox Live Creators Program, you can publish your Universal Windows Platform (UWP) game to Xbox One and Windows 10, but since UWP is not supported anymore, you should look into the ID@Xbox program, which allows you to access the necessary tools and features for game development.
For further assistance, you may want to reach out to Microsoft support directly through the appropriate channels, as the ticket system you mentioned seems to be causing some frustration.
