Yesterday the vivoactive hr did not show distance on my bicycle ride. I put it on as usual. waited for the GPS green light to come one, and did what I have done hundreds of times before but the distance did not work. I stopped and restarted the whole process and the distance still did not work. This morning while walking the distance worked. I do not know what happened yesterday but I noticed I am not an isolated incident as others have had this problem. Please help.
