In the Health Mate app, i've successfully installed on 2 android devices and have 2 users. One user (my wife) can successfully customize the screens that she wants to see. She simply selects the device (Body+) from the My Devices screen, then clicks on "Customize screens". This puts her into the personalization screen in which she can check/uncheck various metrics. For myself, a separate user in the app, I get a totally blank screen when I select "Customize screens". The screen has the title "Personalize your scale", but no detailed items are available for me to check/uncheck. I've tried de-installing and re-installing the app, but this did not resolve the problem.
