Fenix 6x Plus with Wahoo Kickr - no Speed, no Distance

Hi Folks,

I want to use my Fenix 6x Pro with my Wahoo Kickr. I connected the Fenix with the Kickr via ANT. Connection was easy.

So far so good. But during a workout my F6 only shows power. Speed and Distance stay empty.

Does anybody use this combination and knows how to get speed and distance reported on the Fenix?

Thanks a lot

Florian
