Until update 21.16 a graph of my VO2max from running was being shown. Since 21.16 was installed this graph has been empty.
I have recorded the qualifying outdoor run activities (incl. two last week) with Venu 2 and the VO2max is being shown in Garmin Connect. I wonder if something in update 21.16 broke this. I know it included a bug fix regarding the VO2max graph.
