Hello, I've encountered a problem after last syncing of my Garmin Vivofit 2 with my PC. Garmin Connect does not show me any data between May 6th and May 10th, although I was wearing it as usual. It did record the data before and after this period without any problems. It also says my batteries are low and I should replace them. I have read many times that batteries in Garmin Vivofit 2 last for about 1 year. I have had my Garmin Vivofit 2 for almost 4 months, which seems to me way too little time for the battery replacement, compared to other users.
