I see it slide button in the app's Health Settings, and it is on... but greyed out 😞
How do I turn it off?
It's tracking 'steps' and when I am slowly 4 wheeling driving on bumpy Beach surfaces!
Turn it off in the watch. Open samsung health app on watch, scroll to settings at the bottom, toggle off auto detect workouts. The phone version always shows toggled on but only detects what you have the wearable settings set to, so it will still be grayed out and blue.
