I am having the same issue this morning. My walking activity loaded just fine, but my steps are not displaying correctly on the dashboard. They are fine on my watch.
Which device are you all using? The vivofit and Forerunner 15 both track steps, ans I think there something like the vivofit used with company health programs (I forget it's name)
If it's just the browser not showing steps, does it display the other widgets? Have you tried holding the shift key when you refresh (it ignores the cache with the shift key)
