How do you know that the GPS-recording isn’t what you have really ridden?
The map could be wrong as well.
BTW.:
@Beemer did you try to restart your smartphone?
Somtimes, this could help to resolve GPS-sensor issues.
I think GPS-recording should record the actual GPS-position, not some faked snapped to route.
Snap to route for recorded tracks could lead to various wrong results:
- what if you actual rode a parallel street?
- what if you had automatic recalculation switched off?
- what if the street on the map is wrong or outdated?
