Someone testing my game reported issues using an XBox One controller connected through a Bliss-Box 4-play. https://bliss-box.net/ Windows 10 XBox One controller With this setup the input is interrupted frequently. The character in the game will move a small amount or do a small hop instead of a large jump (the game supports holding jump to jump higher). The UI Navigation using the controller is also somewhat messed up with some button presses seemingly ignored. When they don't use that device and plug the controller directly into their PC the input works fine. When they play other games with the Bliss-Box connected it works fine. I know the device uses HID, but I don't know much else about it. The fact that all of their other games work fine and that my game is using the new Input System leads me to think it's an issue with the combination of the system and this device.
