I too have the same issue.
Woodworker X-50 received in mid-January 2022.
Joystick controller doesn’t remember the selected mode after restarting the CNC.
Onefinity Support pointed me to Official Onefinity Joystick Controls (How to changes modes) and suggested updating the firmware in the dongle using the instructions in the link.
Unfortunately the updater doesn’t recognize the dongle when it is plugged in so I have been unable to update the firmware.
