We got one of those Fitbit Arias and so I figured I could just as well set up an auto goal for weight measuring for the fun of it. Creating the goal and such was easy of course, but the first graph that was created didn’t make much sense, and the suggested goal value didn’t make sense either (it was 0.1 I think). After not understanding at all, I clicked around in settings, then went back to the main page for that goal and voila, it all made sense and the goal was set to a value I could relate to.
So this is a bug that I’m already out of, but it was rather confusing the first minute there. Unfortunately I didn’t get a screenshot or anything.
