is there some sort of issue or something or you can't use a ps4 controller at all since it's from the microsoft store?

I'd really like to know if I can use my PS4 control too. I cant find a way to do it so far.

You have to use an input wrapper like DS4Windows to use a DS4 controller. It emulates an X360 controller.

@Ragnawind This worked for me on Day 1, but hasn't worked since

@Ragnawind same as @aruran616 my ps4 worked with "DS4Windows" day 1 and stopped. It works for steam, and all my emulators but not PSO2
