I have a Venu 3S and I notice that when I walk on the treadmill, it automatically classifies it as an activity type of treadmill running. Typically I wouldn't care but because it's classifying this activity as treadmill running and not treadmill walking the miles I walk are not being credited to the 2024 walking – stage 1 challenge. I changed it to walking, but when I do that, I get a pop-up window that tells me some of my data may be deleted by changing the activity type. Why is there no activity type for treadmill walking?
