Xbox-Setups and Settings Between One X and Series X

[Hammerpgh]

I managed to get a Series X last week and so have been testing the game out over a few days whilst still using my Xbox One X version as well for league racing. One thing that I did not expect was that when I changed something in a car setup on the Series X it also changed it on the One X and vice-versa. I thought once the update was done that both games acted independent of each other.

So that being the case I assume that anything I change on one mirrors on the other. That is except race stats and ratings which do seem to be independent of each other. Stats actually do not seem to work at all as anything I do on the Series X does not seem to update my stats but ratings do seem to work.

Am I correct in these findings?
