I purchased the Index S2 two days ago. I did setup in accordance with the guide and manual. It has showed only weight, no weather, no initials, no body fat, no body water % or muscle mass %. Just a question mark over a silhouette. If I just wanted to weigh myself, I would've gotten a cheaper scale not one that cost almost $200.
I did reset, I did replace the batteries and I did cleaned the surface with a cleaning paper (with alcohol).
All my efforts are useless. It is still only displaying my weight and BMI in the app.
I need assistance otherwise I will be returning.
