That forum is one of the places I used. It appears NONE of the fitbits are PC compatible anymore. And they haven't exactly been open about their changes either.I don't know anything about fitbits but if it's not compatible with your PC, how about with your phone? or maybe ask here? https://community.fitbit.com/t5/Community/ct-p/EN
I know that just using an app on my phone to track my steps is often very useful and motivating so I kind of get how you feel. whatever helps!
and why is tech so complicated, dammit.
