Should be fixed with the new update!
Hello! Sorry to bug you, but I just purchased this and am also having the problem where the movements aren't tracked when the window isn't active. Is there anything I could try to get this working?
Edit/update for anyone with similar issues: looks like the dewindowed button pressing just doesn't work with native Windows PS5 controller support! I got DSX/DS5Windows, which emulates the controller as an Xbox controller, and have gotten it working.
