My Versa Lite worked as it should -- no problems whatsoever -- from late March when I bought it until late August/early September, when the sleep analysis function became erratic. I was coached through various fixes, each of which at first resolved the problem for a short while. Eventually, there were no more suggested fixes and I was referred to higher authorities in Fitbit Support. I thought that meant they would entertain my warranty claim. Instead, they told me that the sleep analysis feature was malfunctioning not because of anything about Fitbit but, rather, because I owned an iPhone and the latest version of iOS had been discovered to interfere with the Fitbit sleep analysis function. "It's not Fitbit's fault; it's Apple's fault," was what they said. I was assured they were working on a solution, which I assumed meant working with Apple. However, a couple of weeks has passed, and I get the feeling I'm being given a run-around because I'm told nothing and am unable in searching the internet to find any reference to the failure of the Fitbit's sleep analysis function, let alone one which blames Apple's iPhone for the problem.
