I am using Fenix F and the latest version of Garmin Connect (IOS). However i found all calories burnt in Swimming were not calculating in Active calories. For example, i swam 2000m today (600 calories) which was properly recorded by both watch and the phone app, while the active calories is still 500 today.
does it mean the active calories were solely based on the heart rates? since no heart rates were recorded during swimming for technical reason.
