If you add a second user to your Scale S (I added by sharing to a new account, but I think it is the same as just a second user on main account), when the user tries to get their measurements they get an error that says “Weight only recorded. Try standing differently or having your feet damp or other stuff”… But actually the problem is they haven’t set up their height and other profile data.
This seems like such a common situation (It happened in This thread ) that the app really should have a specific “You need to set up your profile” error message rather than implying some hardware issue…
