Hello.
I just got a Vivoactive 3 today so I decided to try it on a walk, using the walk activity.
Everything went fine except the GPS data being sometimes a little bit erratic.
For the activity, the watch recorded 3,44km and for the day 3,53km / 5241 steps.
My iPhone recorded for the day 3,8km and 5348 steps.
Now, in Apple Health i have 10,7km for the day: the 3,8km from the iPhone are added to 6,9km sent by Garmin Connect. So Garmin Connect sent an incorrect value, summing the kilometers from the activity and the distance from the steps. And it sent those 6,9km with a bad time (the time shown in Apple Health is the sync time) and the data for this day is incorrect.
Anyone else have had this problem before? How to correct this for next days?
