Why don’t I have any gait data?
If the user isn’t walking for a long enough stretch of time, the value would show as zero. To measure a "gait segment", the user needs to walk for a couple of minutes continuously (meaning no stairs or pauses in the walking). But even if there aren't any gait segments, steps are still being tracked. If the user sees data under ‘Steps’, their activity just hasn’t triggered the gait measurements.
