I have an annoying issue with my Watch. I am running OS 2 Beta 5, I think. The latest OS 2 Beta anyhow. When I track a walk I get an average heart rate. When I run or play football with my watch I don't get an average on the activity app. I wear my watch very snug so that isn't the issue. During my hour of football tonight, there are heart rate results in the activity app very 10 mins at least. So if there are many results over the tracked hour, why does no average appear ? Should I just be patient and put it down to Beta software ? Does anyone get average heart rate results from runs ?
