@HonestXO Sadly this isn't the only model of controller that is currently having a degraded experience or being broken in F1 23. I made a thread about the Dualsense too and seems like it got broken at a similar point in time.
Ironically the Dualsense has the opposite issue to the Series controller, triggers haptics are working, but no vibration in the handles themselves.
Was broken in F1 2021, got fixed, broken again in F1 22, got fixed again (albeit Dualsense never got fixed at all in F1 22).
The fact that it is broken again just indicates that they are porting bugs and features from a point in before they had previously fixed it in the previous game.
Not fully related to this issue specifically, but it shows that there's a pattern of controllers not working properly in F1 23:
