Stadia only sensing one controller, when ControlStadia shows 4

[michaelkcpang]

Hi, I'm trying to play "Get Packed" locally with three other players. I have all 4 gamepads connected to the computer and Control Stadia shows all four and I can map all the buttons. But for some reason, when I'm no stadia, it only shows the one controller.

I had the same problem.. i want to use stadia with f12020 a steering wheel and a ps3 controller.. it detects both for one player, but not separately; so i installed paralell to "controlstadia" for the wheel, scpdriver and server for the ps3 gamepad and joytokey to transform it into a keyboard.. tachan.. google stadia f1 2020, the most avanced game in my shitty computer with split screen and 2 controllers!!!

I have the same problem, I have added a second controller, which is correctly visible on ControlStadia, but only one works on Stadia.
I have also tried using a Stadia Controller, but if I connect it with the extension active it is not recognised by Stadia.
