I have experienced this on and off and its only yesterday that I figured out what causes it.
When the footages I use all are within the timeframe of the FIT file, everything is fine.
??????When I have footages that are just before the ride to use as some intro in the video that I am making, when I export, the elevation profile/graph is always missing, but all other gauges are there, include elevation shown as numbers.
Is this by design?
