I have a 6+ . on 8/30 it stopped recording data points for the steps.It is still tracking and sharing with other apps but the graph is just dotted line going from the 29th to the current steps. I have rebooted and taken the steps off the dashboard and readded. I have tried adding the steps under Add Data point and it puts it for a second but reverts back. I thought about deleting the app and re-adding but don't want to loose my stats.
