Hi Everyone!
So sorry to hear about the issues syncing your One. Fortunately, I have some suggestions to help:
1. Restart your tracker.
2. Reboot the computer, tablet, or phone you're trying to sync with.
3. Open the Fitbit app to initiate a sync.
4. If your One is still not syncing, take a look at our help article to learn how to set up your tracker as a new device.
I'd also double check a few things:
1. Make sure that your iOS, Android, and Windows Fitbit app is updated to the latest version. If you're syncing to a Windows device, please keep in mind that we recommend updating to Windows 10 and using the Windows 10 Fitbit App.
2. If you've upgraded to OS 6.0 (Marshmallow) on your Android device, make sure that you have location services turned on in the settings.
3. Is the device you're trying to sync your tracker to on our list of compatible devices?
Those of you who are seeing an error message or the "Fitbit 6.60" message when trying to sync, please take a screenshot of this and attach it to this thread. The more information I have the better I can help!
I hope this helps! Please let me know how it goes.

Hello
I have been trying to sync my One for several hours now, but to no avail. I tried syncing using my iPad (iOs), phone (Android) and computer (Windows 😎 but nothing works.
I restarted my tracker (I get the Fitbit 6.60 message), uninstalled and reinstalled the apps, restarted my devices.... nothing!
The only thing that worked, once, was rebooting my internet connection but a) I find that rather extreme considering FitBit was the only thing/application not working, b) it worked only once.
Could anyone help, please?
Thank you

I too am having this same issue. I sync via computer and have not been able to do so using several computers since last night. You're not alone.

Same problem here. I can see my steps on my One but it won't sync with my Samsung Galaxy S6. It keeps saying "Tracker Not Found". When I try to pair my Bluetooth with my one it says "pairing rejected by one". Super frustrating since I'm in a weekly challenge and doing great. Everything has been working fine for months before this.

Have not been able to sync since yesterday afternoon. I'm at the end of a challenge and need the last 2,000 step added from yesterday to hit my goal. Very frustrating.......

We're sorry for the trouble you've been experiencing with your Fitbit One. If you haven't already done so we suggest restarting your tracker:
1. Plug your tracker into the charging cable, which needs to be connected to your computer. Please make sure that the gold dots on your tracker align with the gold contacts in the inside of the charger. When you hear a click, you will know your One is in the charging cable properly.
2. Hold down the button on your tracker for 12 seconds.
3. Remove your tracker from the charging cable.
4. Press the button on your tracker until the screen lights up.
Your One should work normally. I had to turn my phone off first- then back on. Works!!

I also reset my tracker, however I had to hold the button down 20 seconds, then I removed the tracker in the charger from the usb port. At that point my tracker had successfully turned off. I pressed the button and the tracker turned back on. And I'm able to sync again. The reset just took a few seconds longer.Good luck to everyone.

Thanks @suehilbert but as mentioned in my original message, I'd tried that several times but it didn't work.
It seems back to normal, though. I took my iPad to the office today and was able to sync like nothing had happened.

I've had this problem for at least 6 months. I was told to re-install, reboot, etc. It may work for a day or 2, but then I'm back to no communication. I've spent alot of time trying to get the communication problem resolved. I've given up, I'm unhappy and I won't buy another Fitbit product.

Here's my well-educated theory:
When updates are being distributed (and it's probably a slow process considering how many thousands of people have these devices) the first step is to disable the tracker's ability to communicate with the app. Then updates are applied & they have a way to drain the battery in the tracker so it will restart & the updates will get applied to it when the battery is charged. Lastly they restart communication between tracker and app. I find best way to deal with it is to leave it alone until battery drains, then charge & synch.

mine won't sync either! Two months ago while charging, it went completely dead. I was able to reset it. Maybe they are trying to get us to buy their newer products????

Everything was saved. It just rebooted the device. Think of it like a reboot of your PC. All your stuff is still there.
