I have a Vivosmart sw version 3.50 and GCM 2.14 on a Galaxy Note 4. For the past three days the syncing has been completely messed up. For example, this morning my tracker says I've done 34 steps, but the app says I've done 9562 steps. The last sync was 51 minutes ago. It also says that I slept from 10:54 to 7:48 (US CDT) last night, but it's only 5:41 now - a couple hours away from when it says I will wake up! It reported the same thing at at 4:45 too. I have tried syncing and nothing happens - either nothing truly happens or even though the sync appears to complete, the data does not change in GCM to match what's on my tracker.
I have tried uninstalling the app (twice), but the data comes back and there is no way that I can find to delete the it.
If I change my device settings in GCM, the tracker picks the changes up immediately. For example, I changed my time to be a 24 hour clock, and the tracker immediately changed. So it seems that the tracker and my phone are communicating.
Please help! The app is completely useless to me if all of the data is wrong.
