One won't sync with IOS 9.3.1

[Pdljmpr]

My Fitnit One was working great until I updated my phone. Now it won't sync. I have turned Bluetooth off and on, uninstalled and reinstalled the app, powered down the phone and then on again. I am waiting for the battery on my One to die and see if it will sync after that but would like to get it working sooner if possible. Does anyone have a different suggestion?

I wish I could give you a magic answer -- the "I had the same problem and this is how I fixed it" answer.  But I updated my devices with no problem.

Try restarting your tracker -- don't let the battery go dead before recharging.  Completely discharging a lithium ion battery shortens its lifespan.

Good luck.

Thank you for the tip on the battery. Looking on another discussion thread I was able to solve the problem. I plugged it into my computer and held the button for 20 sac. Then I was able ti sync it to my phone. 😀

Hi!

I have the same problem, but have not succide with heldin the button for 20 sec. It was not plugget in to my computer, only a charge device.
My HR have never been synced with a computer, only the iPhone, so I cant see the point of plugg it into a computer nom.

My problem also started with 9.3.1 update. The firbit help screens says hold down the reset button on bsck of device for three to four seconds. I had to reset several times over the course of the day yesterday.

I am using a flex so this isnt limited to one device but seems related to the ios 9.3.1 update.

nothing done.

My Fitbit is not synced with my computer.  When I plugged it in I just held down the button for about 20 seconds.  It reset.  I unplugged it and it synced right to my phone.  If you are still having issues I recommend giving it a try.

I had to do this multiple times throughout the day yesterday so i wouldn't say this was the solution for me . By later in the afternoon i had no further problems and fitbit syncing regularly finally.

Hi everyone @Knightshotter @Pdljmpr @SunsetRunner @Loke @LZeeW, I'm glad to see you guys around! Good news huh @Pdljmpr, I'm happy to see you're back in business! Thanks for your help my friend @LZeeW .

Well guys, I'd recommend doing the steps listed in the I can't sync my tracker article to see if those steps do the trick.

Give it a shot and let me know the good news!

Fitbit Flex has suddenly stopped syncing and battery run out very quickly.  I downloaded the latest iPhone update and it was fine for a few days so I don't think its connected to that, I only bought the device this January and it's now useless 😞  How do I go about talking to customer services as it must still be in warranty,  Too much money to spend for it to only last a couple of months!

Thanks for the tip. I tried everything else but nothing worked...until I tried your suggestion.

[MarreFitbit]

Welcome guys @HVCBurnett @cwaysom! Did you contact Support @cwaysom? If you've tried all the suggestion posted without luck, I'd recommend reaching them for a deeper investigation. 

Nice, I'm glad to hear that the tips helped you my friend @HVCBurnett ! 

Hope you both have a nice start of the week!
