Unable to set up Fitbit Flex.

[Mamadeer]

I can’t get my Flex added to the Fitbit app. It has been charged, and tried many times to get it to connect with no luck. Please advise.

Hello @Mamadeer, thanks for joining the Fitbit Community, it's great to have you on board. 

I appreciate your participation in the Forums and for sharing your experience with us. Tell me, have you restarted your Flex lately? Are you getting any kind of error message when trying to set up your Flex? Have you restarted your phone and updated the app recently? If so, I would like to suggest you the following:

1. Turn off Bluetooth on your phone; wait 10 seconds, and then turn it back on.
2. Make sure you have a strong WiFi signal and that there are no other Bluetooth devices around that might interfere with the setup process.
3. Restart your Flex again
4. If you can't set up after a restart, reboot your phone or tablet and try to set up again.
5. If you can't set up after the reboot, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your phone or tablet and try to set up the Flex one more time. 

I hope this can be helpful, if there's anything else I can do for you, please feel free to reply.
