So yes I know the functionality doesn't work on a CSW v2.5 right now. However, I initially installed it onto the universal hub, checked the shifter functionality, and the OLED display was working correctly.
Fast forward a month and I decide to try it again, and now the display looks like this:
The picture does it better justice. The display is not lit as much in the middle and on the right hand side of the display. As I haven't even used it yet, and STILL waiting for a firmware update to allow functionality with the CSW, I'm wondering if I just need to send it back to Fanatec for an RMA/Replacement.
