I have a Versa 2. App latest version has lots of random data added, but seems to have lost a simple step counter for the day! And the fitbit itself dies after 4 hours of use. So it's telling me I've been stationary for 75% of my day, when the truth is, the fitbit only works for 25% of the day!! Help!!! I will never, never, never buy a fitbit product again.
