Fitbit Charge 4 not syncing since April 7th

[doma929]

My fitbit charge4 haven't synced for the last 3 days. I tried to reboot the device, reinstalled the application, but nothing seems to work. Is there any work around? 

Also, I wanted to chat with customer support, but customer support page is returning error. https://myhelp.fitbit.com/s/errorpage?language=en_US

Hi @doma929 , for Customer Support try this link: https://myhelp.fitbit.com/s/support

One thing worth a try is to set up your Charge 4 as a replacement device.  (Do not remove the Charge 4 from your account first!)In your app click on the little icon/photo top left to go to the account screen.  On that screen scroll down to + set up a device.  From the drop down list of devices choose Charge 4.  You will get a message: There is already a charge 4 connected to your account; do you want to replace it?  Confirm that you do and continue following the instructions.  If the app can find your Charge4 it will automatically sync.

You may want to move other Bluetooth devices out of range, and also if you sometimes sync with different devices (e.g. sometimes a tablet and sometimes your phone) make sure that Bluetooth on the other device is turned off as that can also interfere with syncing.

I hope this helps.  Welcome to the forums!

Same issue. I observed that this happens only when I am on wifi. If my Samsung S22U is on mobile data everythings goes well.

It's not a watch/device problem. I think it is an app. problem. I syncronised my wife watch. Same issue.

It logs me out everytime I am on wifi.

Mine doesn’t sink either. I think it’s been weeks since last time it sinked.

Thank you Julia!

I troubleshooted the problem with fitbit support team, and it is now syncing without problem.

The general steps were same as above.

I tried this it didn't work for my watch

So I tried this. It worked, but all the data from the previous weeks that failed to sync, such as sleep patterns, were erased. It’s so disappointing 😔

Hi, @MEAWW  your Fitbit can store detailed stats (like sleep scores etc) for a least 5 days.  It will store basic stats - steps, heart rate for 30 days.  However, if it does not sync for more than 30 days, you will, unfortunately, lose data.  That is because the device is too small to hold memory for more than 30 days.

Thank you Julia, it’s good to know

This seems to have been a problem with all Fitbit models right from the start and the company has never been able to sort it out. If you ask for help they will just get you to reboot your phone, reboot your Fitbit, turn WiFi off on your phone, turn WiFi back on again, same again for BlueTooth.

One thing I would not recommend is to reinstall the Fitbit app on your phone - I did that once out of complete desperation only to find that the latest version of the app was not compatible with my (four year old) phone. It took me ages to find an older version of the app (not on the Fitbit site).

This afternoon I literally hit my Charge4 with a hammer.   Now I don't have a tracker anymore, but it's for the best, because it wasn't good for my blood pressure for performing such a seemingly simple task as getting your fitness tracker to readjust the time displayed to account for a time zone change to turn into a saga that involved attempting a sync that also wouldn't work, which in turn required stabbing around in the dark for hours on message boards such as this one, trying to find out why in the heck your tracker won't sync, trying one thing after another -- turning bluetooth off, turning it back on, restarting my device, deleting the app, reloading the app, trying to download an update that wouldn't download (and yes, my internet connection was 100% fine, so don't even ask), and having none of those recommendations (in the recommended sequences of steps) solve the problem.  This was my second FitBit, and it amounted to throwing good money after bad, and I will NEVER, EVER buy another one again.

Bluetooth on my tablet had to be turned off.  Worked instantly.  Android phone wi-fi working fine since yesterday.  My charge 4 previously was being synced to the tablet, but was removed and "forgotten" and that wasn't good enough.

This did work, it only took me about 45 minutes to get the Charge to reconnect to the Android, it looks like another phone "upgrade" has rejected my Charge 4, possibly because I have just subscribed to the fitbit premium, I went through the sequence you suggested and it took about 30 minutes before the phone would connect, I'd just given up and was going through looking for more help here when the charge 4 suddenly displays the connection code.  The phone wasn't looking for it so I had to restart the device connect function and got asked if I would allow the fitbit app to access the data.  Eventually it seems to have restored everything so hopefully this will keep working for a few more weeks until Google "upgrades" things again.

I saw the sync issues on the phone while I was on an Elliptical getting my "hourly 250+ steps activity" done at 2pm, the Fitbit showed the step count for 3 minutes but when I finally managed to get the synchronization issues fixed, the Fitbit app updated to the step count to match the Charge 4 count but now is showing that I did no exercise during the hour that it took to get this fixed.
