PS4 Controller not working with Xbox (beta)

Maybe clarify that you meant the app.

Yes, that is true. PS4 controllers don't work on Xbox.

I have always found only authorised xbox controllers worked with the xbox app streaming. From wireless dongles to aftermarket 360 wired controllerd if its not official it didnt work.

You can use DS4, works with it.

I had this issue and found an answer

all you have to do is go to ds4 windows and

click on controllers it should take you to profiles [whichever current one you are using] click other and make sure the controller tab under the bt poll rate is set to xbox 360 [also set your bt poll rat to 1 ms this isn't really needed tbh]

anyways that's the fix hope this works for you like it did for me
