Hi,
steps always are counted as summary of the day - counted inside fenix 5S and in Garmin Connect Android App.
In case of activities (with GPS or Indoor), in Android App Garmin Connect the steps are cumulated in field "Steps", but additionally, a new colored field for each activity is added with all data.
But where can't find the done steps for this special activity??? (I found Time, Distance, Calories ... But unfortunately not the quantity of steps for this special activity).
(But is must be saved somewhere, as during export of data to another App (YAZIO), every activity is shown with Steps+Distance+Calories separately.)
