Keyboard and pointer permissions required for gameplay issue
I tried several operating systems (Win 7, win 11, linux mint) and browsers(chrome, edge, supermium). I've even tried playing around with chrome settings, resetting to initial settings. Nothing helped, two hours of agony. It works well on TV fire stick. However, connecting a mouse and keyboard to it falls off, especially as the gamepad in kingdom come seems unintuitive to me :(
Edit: Apparently the luna team has solved the problem. For future generations to whom this post pops up in a google - wait a few-odd hours.
