I am so upset. My versa lost it's charge incredibly fast, now it won't charge, and gets really hot on the charger. I made sure the charger and back of the Fitbit are clean. I tried restarting it & the 3 button factory reset. None of this worked, it is just dead. I got it for Valentine's Day, so it is only 5 months old. Any ideas of what I should try next? Super bummed.
