In recent weeks my vivosport developed an extremely frustrating condition where sync drops recorded activity, that is:
1) Step counter is reset from a high number to a very low number (on one day it dropped the previous day number to zero).
2) Recorded activities are lost.
The step counter issue is happening daily. I have to force sync multiple times to have the same number show in Garmin Connect phone app as is displayed on the vivosport. For example right now "Real Time Data" on the phone shows 1982 steps which is the same value as displayed on vivosport, but as soon as I sync in the app, the number in Garmin Connect drops to 93.
I've hit recorded activities being lost yesterday. When I have tried to sync after a workout it had failed multiple times, and when it finally succeeded the activities where not shown in Garmin Connect app nor website. Further syncing multiple times, including over USB did not make the show up, so I believe they are now completely lost. The only record of them is the summary numbers on vivosport in "Person" > "Folder" menu.
Is this something on Garmin's radar to resolve in software updates any time soon? As I said this is extremely frustrating as the most basic functionality of the device is lost when I cannot see the data after activities!
