How do I reset the game to start over?

I have found no help online to restart my profile.

I tried what worked with the previous forza game but that combination of buttons does not work.

I’ve deleted my save on my Xbox one but that does not work because it re-downloads it from the cloud.

So please help

You need to go to the manage game page (menu button on game tile) and delete the game save from everywhere. This will remove it from the cloud and the console.
