I've been using last official software release. Everything was ok since last week - I went for a ride and after some time I observed that my distance is 0.01 KM. Tried to stop activity and run again but watch was frozen on discarding screen for more than 5 minutes (actually I tried again for many times and even after night it was not completed). I tried the same with running - but received the same situation. What is interesting - segments distance was counting down so I don't think it's hardware issue. So I didn't wanted to restart my device to factory settings and I installed newest beta release - WOW - it fixed problem .... for 4 next activities :( Now again rides/runs distance is not calculated (is calculated when doing pool swim) , watch is frozen on discarding/saving of any activity (even pool swim).
I'm pretty sure that hard restart would fix the issue but I don't want to loose all my settings and data - any advice ? Maybe delete segments? I'm taking triathlon in next 3 days so I'm a little bit confused.. and it's not first issue with this crappy watch.
