Uchikoma: I've got a fix for this under Windows (so Legion Go users): the system sees the controller as two separate devices, having a second controller attached to the system used to cause this problem back when the game was originally released. This led me to tinker around a bit and:
- Go to Device Manager
- Exoand the Human Interface Device category
- Disable the HID-Compliant Game Controller
The radial menu is now working for me (I disabled then re-enabled the controller via the in game menu after doing the above steps). Item selection is on the left stick once the menu is open.
With HID Compliant Game Controller disabled, Windows still sees the controller as a Xbox controller under Device Manager.
NOTE: You lose access to Legion Go buttons while the above is disabled, but the HID Game Controller can be enabled and disabled without reboots so it's quickly resolved.
LEGEND! Thank you this fixed my issue - I was having the same problem using my 8BitDo Pro 2
