When I got my Fitbit back from you and tried to sync it, I came across the Windows 10 unable to sync issue. I paid $100 for repairs but now my watch sits on a shelf, completely unusable. I know its not your problem but you would think someone there has heard of this issue and could have given me a heads up - if they had, I wouldn't have gone ahead with repairs, I have just basically thrown away $100. If I cant sync, I cant correct time, date, settings or anything else so my Fitbit is now useless. Your customer service was great, except the repeated suggestions that I go into advanced settings to correct problem. If I cant sync, there is no such thing as getting into advanced settings, aren't your techs aware of this? Bottom line, thanks for repairing my Fitbit, but I wish I hadn't.
