No calibration on IOS App?

I tried to use wahoo ant+ Stick and Garmin Running Footpod with the original Apple Lightning cable. Works fine, the pod connects to zwift and i can even run with it, but it seems there is no config button in the IOS App for the calibration process! I am running at 10km/h but zwift just shows 1.8-2.7km/h… When using the pod with my garmin watch, it is working fine… and ideas?

Just an FYI, the Lightning cable with an ANT+ dongle is no longer supported and you are very luck to even have it working.
