Flex2 won't sync since latest app update

Replies are disabled for this topic. Start a new one or visit our Help Center.

 Since the App update this week my phone can't find my fitbit and the App won't sync. I've emailed Fitbit but they say it's my devices!! But they were fine before the update. Please help!! Can I go back to a previous version?

Before looking at going back to the old version of the app you might want to try restarting your phone and then restarting your Flex 2 by:

 

  1. Plug the charging cable into the USB port on your computer or a UL-certified USB wall charger.
  2. Remove the pebble from the wristband and press it into the compartment on the charging cable. The pins on the charging cable must align with the corresponding pins on the back of the pebble to lock securely in place.

    You’ll know the connection is secure when the pebble vibrates and you see the indicator lights blinking.

  3. Find the button on the charging cable below the tracker compartment.
  4. Press it three times within five seconds. The tracker vibrates each time you press the button. A few seconds after the third press, all the lights will flash simultaneously. This means the pebble has restarted. If you miss the light flash but notice the pebble has resumed charging, that too is confirmation that the restart was successful.
  5. Remove the pebble from the charging cable and insert it back into the wristband.

I've seen other posts with syncing issues after an update and the restarts can help resolve this.

Thanks. I've done that. Now the Flex2 is coming up on my Bluetooth
connections but the App still won't sync.

Thanks. I've done that (several times now) and my phone is finding the Flex2 but the App won't sync still. And I've just had another app update run!

Another thing that has worked for me in the past is to go into the phone's bluetooth settings and "forgetting" the link to the fitbit before trying the sync again.

 

There are also some more things to try in fitbit's troubleshooting guide for syncing issues at: https://help.fitbit.com/articles/en_US/Help_article/1866/
