I have trouble installing my Tacx speed and cadence sensor. In Tacx Cycling training app I see see my speed, but there is no registration of cadence. When I try to register the speed sensor in Zwift, nothing happens at all (doesnt register speed or cadence, just stopping up).
I have installed the cadence sensor on top of the frame, not inside of the frame, due to the narrow space between my Cannondale Caad 9 frame and Ultregra crank arm. Is this the reason why I cant get the cadence? If so: is there any way to solve the issue with narrow frame? Will enclose pictures of the setup and the app.
