Activity 17160221247 is of Alpine Skiing type. It shows 10,923 ft of “Vertical” in the mobile app, but only 25 ft of “Elevation” on the web site. The getActivityById() endpoint is returning 7.0 under “total_elevation_gain” (only parameter in DetailedActivity we can use to derive elevation or vertical). This is resulting in wrong data displayed in our application and we cannot explain the difference between the mobile view and web view on Strava. Can you please look into it and tell us how to fix the problem? The activity was recorded on Slopes and uploaded to Strava.

That’s not really a bug, elevation is the cumulated ascent (that does not count anymore in alpine skiing) whereas vertical is the descent. The API and the website simply lack returning the vertical stat. And I should note the API uses the metric system (7 m).
