Why is so Fitbit so bad at multiple time zones??

Guess what, people get on planes and travel.

Every time, my Fitbit gets so screwed up, including things like changing previous step counts, or duplicating an entire day of steps.

I understand MTZ is a tough problem, but this is just unacceptable. I'm not obsessed with my steps, but when your product is all about counting something, seems like you should be more careful to avoid double counting or not counting at all. Seriously, how much R&D have they invested in their hardware and apps, but it completely fails when you travel. Get it together!
