Wahoo Kickr 1 Calibration

HI guys

When I tried to calibrate my kickr before this morning’s race, the spanner was missing.
I had it linked to the “FC-” number as is the norm, yet the calibrate button was missing.

Is this an issue with the new upgrade?
Usually I have two kickr options to connect to (being the gen 1 kickr), with the non-FC one being the issue with calibration. Now they both are.

Any advice?

Thanks
Brad

Don’t use Zwift to calibrate your trainer. Zwift themselves will recommend to always use the manufacturer’s app to do the calibration.
