Short 4 mile walk today - recorded as an activity (Walk).
Connect data shows negative values for minimum and maximum elevation - this is also reflected in the elevation profile graph which shows the entire walk as being below sea level!
Actual minimum elevation approx' 220' and actual maximum elevation approx' 490'.
Instinct was worn underneath a light sweater - would this account for the above?
First time it has happened - all other walks recorded just fine. On these the Instinct was worn without being covered by a sweater.
