apple health sync

when I you going to fix apple health sync?

it overwrites data I apple health every time you open Garmin connect.

this images showed that Garmin is at fault here

I took an index bpm reading 07:24 and synced with connect, then I opened Garmin connect 11:09 and it synced it again. 
This behavior is not ok it overwrites data this means you only get one index reading every day, only the last!
