The question is pretty descriptive your app does nothing with my 800 dollar watch. It used to now it won't do anything!! It won't track anything past the current day it won't track my sleep body battery anything I can start a challenge or accept a challenge but it doesn't track my steps very pissed right now I have been wearing a Garmin watch for the last 6 years and now it doesn't work. I have an inreach and dog tracking and training collars through Garmin I hope I don't start to have problems with those items if this is how things look for the future.
