Can't save in any X360 games launched in Xbox Cloud Gaming

Everything works without any problems. So what I had stored on the Cloud on the X360 I uploaded the same save files to Xbox One. It's a good idea because the X360 games can't store on the new Xbox One system.

After testing this myself, I think that currently the only solution is still as Foamy036 stated: Have the save for the Lock-on content created on an X360 saved to the Cloud. On the XOne, S&K doesn't seem to see the other games (probably due to the different
save structure of the system, which would require a modification to the game itself, making it an XOne-unique update which won't happen to an X360 game), so can't load the Extra content without the save already existing on the cloud.

How to setup cloud save games will guide you. You can also get the app from the Store to save any screenshots you have.

Edit oops that link is x360 but this Cloud save games FAQ
is for XBox1

Sem problemas, seu save fica guardado na nuvem.

Com o save na nuvem, você pode utilizar ele em qualquer console, inclusive no x360.

[Translation-No problem, your save is stored in the cloud.

With save in the cloud, you can use it on any console, including x360.]

your cloud saves are associated with your xbox live account which is not specific to x360 or x1. when you start playing an x1, your cloud saves made from an x360 arent going anywhere. you wont be able to use them on your x1, but they will be there for when
you log into an x360.
