WSA now has compatibility for games with joystick, and the input is mapped to the WASD keys. The arrow keys can now also be used as inputs for aiming and sliding in games. The update also brings improvements in scrolling, making the experience smoother. There are also minor networking improvements for apps using the internet. The Android minimum window size default is now set to 220dp. Finally, there’s a new toggle for the diagnostic data in the Windows Subsystem for Android Settings app. Again, this update (version 2206.40000.15.0) is available on all insider channels, but some users might face issues with their VPNs, not working with Advance Networking. In that case users are advised to disable Advanced Networking from the WSA Settings app.  You can read the full changelog below.
