Version 1.39 just arrived on my Zwift-dedicated PC (Win 11). I notice that in the new pairing screen there is no longer a calibration option for the steering device. A small wrench icon used to appear to the left of the steering icon on the pairing screen. Clicking the icon after pairing the device allowed the user to centre the front wheel manually. Is this disappearance intentional?
I’ve used a Elite Sterzo Smart since Q3 2020 (in an older and now a newer Zwift account) and found that zeroing calibration very useful when running the Sterzo Smart without its spring (for a lighter steering experience). Perhaps the calibration was seen as unnecessary for a non-modified device. 
Out of curiosity, do the other steering devices on the market use correct-to-centre mechanisms? I’ve only used the Sterzo Smart.
