A few reviews have pointed out that step counts have not been displaying correctly since October 25. The last update to your app was September 25. Coincidence? I'm experiencing the same issue. My Up band is working fine. Sleep will display if you manually add sleep / awake times. The app will show your recent heart rate, but no heart rate or step count data are stored by the app or the servers. Only sleep data is stored. I'm using an UP3 with Android app on an HTC 10 phone running Android 7.0 (Sept security patch). Please fix this! Well done!!
