heart rate zones-why activity isnt loggin correctly
New watch about a month old. Most days my 75 minute indoor cycle logs as 75 minutes. Some days it barely registers. Today it logged 46 minutes. I’ve changed the zones to reflect my fitness levels. I have googled and watched a ton of videos and am no further ahead. Why doesn’t it log entire 75 minutes if I’m within the zone . Got to be doing something wrong
