GPS data missing after sync

[fcano]

Went for run with Blaze. Started run activity from blaze screen.  Finished and sync'd with iPhine app but internet connection was spotty.  During sync I could see the activity had gps data (the map showed on the iPhone). Later when internet was stable and sync completed the GPS was gone and all I had was the HR data.  Also my the activity never showed on Strava

Great to see you around @fcano. During the exercise, was your phone's GPS on? Keep in mind that you need to have your phone's location on in order to see your exercise map. Regarding Strava, your activity wasn't transferred since there are some activities that won't sync to Strava like:

• Non-GPS activities 
• Previously completed activities
• Duplicate activities that is, if you already recorded an activity with Strava, a Fitbit activity that occurs at the same time won't sync.

Hope to hear from you soon.

@AlejandraFitbit I believe the Blaze has its own GPS and does not require the phone GPS. Correct?

the activity initially showed GPS data on in the FitBit app but later if did not show up.

The Blaze does not have its own GPS, but depends on being connected to the phones Gps. 

When connected, there will be a phone icon on the Blaze. If a line is through the phone, it is not connected.
