Incorrect Heart Rate Syncing with Connect App

Is anyone else having issues with heart rate being synced from the Edge 840 from before you have started an activity. I use a Polar H10 and constantly get up to 8hr of readings added to connect from before the activity (or the heart rate monitor is put on) duplicating what looks like the first reading of the activity taken. I have enclosed an example of a day I did 2 rides. This screenshot is from the online connect health stats page showing a constant of false readings up and till the activity starts.

  • Wow. That really is spectacularly wrong. In answer to your question, I'm not seeing anything like that using my Garmin HRM Dual and Edge 840 or if using my Fenix 7 to Broadcast HR. Could you try disconnecting your H10 from the strap until you are ready to pair it and then see if you get the same result?
