First time I synced it got stuck perpetually syncing but when I deleted app and reinstalled its been working fine. However there is something wrong with the "most frequent zone". Color is correct but it indicates zone one when it is clearly zone 2 (of 3) On my wish list I would like to see time in each zone... Not just most frequent zone. Also please have the option to turn off daily goal as I only use this for heart rate tracking... Not activity and I dont like the data clutter.
