Distance differs in application

Distance differs in application

Hi there,

I am using Chigee aio-6 max.  Yesterday I noticed something strange. I rode 169 km in 2 hours 9 mins with my bike  and saw it in BMW app. ( Picture 1 )

Then I checked in Chigee app. In the apps general bike record page it writes 105,7 km in approximately same time 2 hours 15 mins. (Picture 2 )



But when you click that ride ( with the map page ) it seems as 170,25 km. (Picture 3 )


So why the main page does not show the correct ride distance? Any ideas?
