Question: how fitbit versa 2 works?
Answer: The Versa 2 has one button on the left side, ditching the three-button setup of the original Versa. ... On the Versa 2, those actions can be done with a tap and a swipe on the display, while the single remaining button acts as a back button when you're in an app and triggers Alexa or Fitbit Pay with a long-press.
