Before the 2026 season pack, all changes to stuff like LED profiles and telemetry readouts worked perfectly fine on my Fanatec GT DD Pro w/ Formula v2.5 rim. However, now the game is not sending any information to the wheel and Fanatec reverts to as if there is no profile set at all.
When in the pit lane, the correct LEDs will show, however the centre display will flash between '{P}', '655' and an ever increasing lap count every 1s or so. Once on track, the centre display will sometimes correctly read my speed, but sometimes jumps randomly to a number like 500. The LEDs will also disable my profile and revert back to as if I had no profile loaded.
This has never happened on any other game, nor was a problem before the DLC. I believe the telemetry hasn't been set up correctly in the backend. I have the UDP ports set up correctly and the Fanatec LED option enabled.
