Although it is supposed to be working, the trainer calibration button within Zwift is not available. I upgraded to the latest firmware of the trainer and used it in zwift several times now, I never see the calibration button.
I use a Windows 10 PC with and ant+ USB adapter. The Tacx flow ist connected as the controllable trainer and power source. For cadence, I use the wahoo cadence sensor as it is more precise.
What am I doing wrong?
