Yes it is the S2 when I weigh in if you hit the + sign you can see its registered however doesn't upload to front page until you reboot the app which im told is wrong compared to others , it should upload when synced
When I manually enter a weight in the app, the "front page" does not update (and still shows yesterdays weight) until I leave the app and come back in. So that's the same as what you are seeing. It's been that way since the new app update.
Your's probably does upload but the new app has problems and loses it's mind until kickstarted again.
