I just purchased the new Xbox series x/s controller and I have been able to connect to pc and play just fine on chrome. However on IOS the controller will connect to my iPad but I will not be able to register Input with Stadia on safari.
@Heyheywow Currently the new Xbox Series S/X controller is not yet listed under supported controller for Stadia

It might come later in the future, but as for now I suggest using a supported controller listed on the link above if you have one.
It’s also not working with the regular Xbox one controller via Bluetooth.
controller connects to Bluetooth on iPhone fine.
When trying to play game via Stadia through Safari a message is received that there is no controller detected.
