The first time I noticed looking at the reading of the pace a couple of minutes after the pause - it was 0.0. I waited and after a few minutes the pace turned itself on. As a result, the pace on this kilometer was more than 9 minutes. The second km at the same spm was normal - 6 min.
The second time was today. I pressed a pause, stopped to say hello to a friend, after that I pressed start and after 20-30 seconds the pace was 0.0. I done again pressed stop / start and the pace went to be considered. The current kilometer has been destroyed.
Dear Garmin, you should already pay me for debugging your crooked software.
