Total of 4 days riding, stopping recording at each end of day and leaving it on sleep mode.
Restarted the computer on day 2 but in the middle of the day of day 2, changed navigation to a shorter one. same end of day stopped and turned it to sleep mode.
Day 3 is the same but changed the navigation mid day also similar to day 3.
Day 4 did not change navigation.
What ended up happening is the total distance is recorded but day 2 and day 3 data is not shown in the maps and checked with the fit file also (similarly, the file was small so i was afraid that no data was indeed recorded for days 2 and 3)
Also in the 840, the summary stats will not show and shows the error: failed to load ride details in the screen
Stats:
Day 1 and day 4 complete
Day 2 and day 3 no data
total distance of 654.3km is correct, but all points were skewed due to the lacking day 2 and 3 data. e.g. ave moving time etc.
they highlight this feature that you can change navigation to a new course midway your ride but if this bug keeps happening, i will not change the course or navigation midway anymore. what a waste of money upgrading to an 840 from a 530 if it is indeed this case
