Dumb noob Forza 4 question…

[Hard-Drive]

Total newbie to Xbox here. I recently bought a second hand Xbox One X for my lad, and installed Forza Horizon 4 via a very slow overnight download on a game pass. I played it a bit on “his” profile before realising I can set my own profile up on the same game pass.

Is there a way I can “reset” his Forza game back to the very beginning without either affecting my progress or having to reinstall the game?

I’ve googled, but it either doesn’t seem to match the options on the console, or it’s for PC.

Thanks.

You could delete the local and cloud saved data for his profile, which would erase everything for him aside from achievement progress.
