For about 4 weeks i have a strange problem with my fenix 5x and i cant find it. Sometimes when i record a bike activity the watch doesnt record speed from my speed sensor (i already reconnected the sensor and re-paired it with the watch) and so my recorded distance is completely wrong.
But shouldnt the watch take the distance from gps and not from the speed sensor?
I have shared one of my activities here:

my girlfriend recorded the same course but got a distance of 76,4 km
Is my speed sensor broken or is there something wrong with the watch?
