My flex won't sync

[Eliciajo]

Last night at 3:55 pm my flex stopped syncing.  I thought it needed to be charged so I charged it.  This morning I realized that even though it was fully charged it still was not syncing.  I came to this forum to try to find a solution but I have tried every solution and nothing has worked.  I have re-started it, I have turned off and on the bluetooth, turned off and on my phone, I have logged out of the account, I have force stopped the app, I have tried every solution here and it still says it is looking.....  It appeares to still be tracking as the dots are increasing as the day goes on.  Please help.

I don't have any advice for you, but the EXACT same thing happened to me at about the same time yesterday (EST). The lights are flashing, but no exercise has been recorded since, and no sleep was recorded last night. I can see my sleep stats on my PC, but not the exercise. I can't see either on my iPhone.

I had the exact same problem that started a few days ago. I called Fitbit and was told I'd new a new one. 

Funny how it happens when the flex2 came out 😡

Yes happened to me to  tracking but no amount shown on the app what's going on ... customer support are no help !!!

Same thing is happening to me this week 

[lsuss]

Exactly. I was told it was a problem on the Fitbit end and their engineers were working on it...we shall see. I am getting stats on my pc but not on my phone.

I have the same issue. Mine last synced yesterday afternoon. It has not tracked my sleep, exercise, or my steps since then. I'm kinda upset because I went to the mall to purposely see how many steps I could get in and it didn't track a single one. Not happy.

[MNguerita]

Same here....😩 Guess for now I will see if the engineers figure something out.  Not a happy camper.

Just got off the phone with customer service and mine is working fine now. They just had me to go to my settings and cut my blue tooth off for about 10 seconds and then cut it back on and it started to work. Try it and see what happens. Merry Christmas and have a blessed day.

[lsuss]

Tried that but it didn't work. Thanks for helping, same to you. Happy new year!

Nope, I try that and Flex rejects the pairing. I haven't had it sync in days.

[lsuss]

Same. Only on the pc.

Thanks to all Fitbitters for popping by the forums and a warm welcome to our new friends! 

When having syncing issues you have to check a couple of things: 

1. Full/medium battery for your Flex
2. Internet connection and Bluetooth on for mobile devices
3. Compatible device, check the list here http://www.fitbit.com/devices
4. Good attitude 

Try to sync only with one device at a time when troubleshooting, this means turning off all other bluetooth devices or computers and leave only the device that you're going to use.

For the ones that are using mobile devices, turn off the device, force quite the App, delete Flex from the Account and also from Bluetooth (reboot it once or twice if Flex keeps appearing under Bluetooth). Restart your Flex a couple of times and after that try to set it up as a new device follow the options for different devices here in this master post from @HelenaFitbit.

Also check your phone Permissions and leave location on to keep syncing with your phone, for more info checkthis suggestions from @ErickFitbit. 

If you encounter any issue, verify the steps and contact Customer Support in case that you're having syncing issues to often. 

Have a great day and I'll be around in case that you need more help!

You know, it just occurred to me that my Fitbit band stopped syncing with my iPhone last week the same day I downloaded the new iOS operating system. I wonder if that has anything to do with it....

Thanks for getting back @lsuss. It is odd that it is nos syncing after the update but not totally crazy! Did you try the steps given above?  Are you getting an specific error, any other detail will be appreciated to further investigate! 

I'll be waiting for your reply! 

[lsuss]

I have tried absolutely everything. Now my stats aren't even showing up on my pc. I'm going to buy the new flex band, which is probably exactly what they expect me to do. Disappointing.
