The Garmin Connect site and app does not register heart rate on "my day" heart rate section during activities recorded with another Garmin device, although I have physio true up enabled. The heart rate is recorded normally in the activity itself.
In the attached screenshot, during the first activity I had the 945 monitoring HR as well with the chest monitor. (Observe the gap in the HR Details page)
During the second cycling activity I have the 945 completely off.
Both activities where recorded with edge 530.
Physio True Up is on on both devices 945 and 530.
I believe this to be a bug of the site and application algorithm, where the HR of the preferred tracking device is only recorded in the all day HR graph.
Thanks in advance.
