My Versa 2 did the update for the Oxygen Sensor. It was working for a bit, then it stopped. Now it just shows “- - %”. Anyone have an idea what’s going on?

Not sure but i think it only works while you are sleeping. Have you slept with it yet?
Best AnswerYes. I've slept with it on, and it still shows no reading. I've cleaned the back of the watch with alcohol, strapped it on my wrist loose and tight, and still no reading.
