The vertical scale was always narrowed down around my actual weight. For example 82-88 kg. This way, I could easily see the changes over time.
This morning, my weight was just a horisontal line. Because they have changed the scale to 0-100 kg, which makes it absolutely impossible to see any short term changes in weight. I wonder if this was on purpose. It is unusable.
I know that there were a lot of complaints about not being able to set the scale manually, which could be especially disturbing when browsing back through earlier periods and having the scaling change for every page. I tend to agree to those complaints. But setting the scale to 0-100 is not the solution to that.
