App only capturing half of my run

[Ashcan324]

My Fitbit app is not capturing my full run data anymore. I run 4 miles daily and this week my app has only captured the first 20ish minutes of my run and then stops.  It is still logging the steps, but not the data associated with the rest of my run; time splits, heart rate.  What's going on here and how do I fix it?

@Ashcan324 Hi there. Thanks for the details mentioned. 

Please verify the following requirements; then try the troubleshooting steps if necessary.

• Make sure that you have a clear view of the sky when you start the exercise. Environmental factors, including tall buildings, dense forest, steep hills, and even thick cloud cover, can interfere with your phone’s ability to connect to GPS satellites. If the signal is blocked—either because you're indoors, underground, or due to another reason—GPS won't work.
• Confirm that Bluetooth on your phone is turned on, and your device is connected under your phone’s Bluetooth settings.
• Make sure that phone is within 30 feet of your device.
• Make sure that your device can sync with the Fitbit app. For more information, see How do Fitbit devices sync their data?
• Confirm that the Fitbit app can use your phone's GPS sensors. For more information, seeHow do I allow my Fitbit device to use my phone's GPS sensors?

Troubleshooting steps: 

See if GPS connects after each step

1. Force quit, and reopen the Fitbit app to refresh the connection with your device.
2. On your phone, go to Settings > Bluetooth and turn Bluetooth off and back on.
3. Restart your phone.

Hope this helps.
