Sense won't sync with the iOS Fitbit app

[barberzzzz]

Sense becoming increasingly unable to sync over last week or so. Refusing to sync at all now. Have followed every piece of advice - resetting, turn on and off (both iPhone and Sense), removing and reconnecting device, forgetting device from phone Bluetooth, deleting and reinstalling app. Nothing working. Also always been inaccurate on floor counting but today has stopped calorie tracking. All very frustrating for a long term Fitbit devotee. Any ideas what else I can do before I demand replacement? Thanks

It seems the only way I can now get my Fitbit to sync is to force quit the Fitbit app, shut down my phone (iPhone 12 pro) and shut down my Sense then turn them all back on. I’ve given up on taking readings for the PAT study since syncing doesn’t ever work. Any clues on if there is an update to fix this? Or if submitting for a replacement is a better option? I’m getting so frustrated I started looking at Apple Watches.

Occasionally there are a couple days with promise but when you look
closely, not all works. The SpO2 hasn't made it from the sense to the
mobile app in 3 days. There have been continual problems syncing. Sometimes
the info that is on the app, reverts to an earlier place making it
incorrect. They definitely don't have the problems solved but glad to hear
that you have 4 days. It's been a while since I have had that success.

[roblharding]

I'm glad someone has had some success. Enjoy it while it lasts. It will end soon. They have not solved anything.

I have the same problems as barberzz but for 2 weeks now with only very limited success. The SpO2 has not made it from the watch to the phone app in 3 days. Always prblems syncing. The info that makes it to the phone app reverts to an early stage with no reasoning or warning which makes it unsuable and worthless.

I got thru to customer services and they advised to delete app and reinstall as they had released a new version since then it’s been good as gold 

[roblharding]

I'll give that a try. Why not? I've tried everything else.

[baroque_nomonet]

I just tried this and it seemed to work for me. Hooray!

[barberzzzz]

Thank you for this. I did the same and so far so good! Happy fitbitting.

Did you try deleting the mobile app and downloading it again? Another user
had suggested that and I did it and the app has worked 1 day in a row now.
I don't know how long it will last but it is the only success that I have
had with the app.
Try it. Delete the app from your phone, go to the app store and
download the app again ( supposedly they have updated it ). When it comes
to join or sign in, just sign in. Go to set up a device in the app and go
through all steps. Good luck.

[jjddhh]

yes I did exactly that

How many apps do you have on your phone that synch just fine every single time with blue tooth?  Many?  Me too!  No problem.  This isn't experimental technology.   Until a few weeks ago this technology also worked with this $300 "smart watch" and now it does not.  The problem here is not me, nor my phone.  It's fitbit.  Glad they are doing everything they can to fix it.  If you missed the sarcasm it is there.

I"m still good, day 7, i think.  No syncing issues.  As quickly has the problem appeared, it has disappeared.

After 4 days, and several attempts to simply delete the app and reload, I did the following to get resolution:

1. Turned off Sense

2. On iPhone, Removed the Fitbit App (long press on icon till minus sign appears, click on minus sign, say yes)

3. Shutdown the iPhone entirely (Settings, General, at very bottom press shut down)

4. Turned on the Sense (hold left button 3 seconds or so)

5. Turned on iPhone (hold on button 3 to 5 seconds or so)

6. Went to App store, found Fitbit App, reloaded onto iPhone

7. Opened App, and signed on to my Fitbit Account again

8. Several questions appeared including connect to Sense by Blue Tooth, I answered yes.

9. By the time I finished answering the various questions, I noticed the app syncing.  I lost two days of data, but I am now back to seeing proper operation with two straight syncs.

Another note to users.  There are other 2nd party Fitbit apps that will transfer your data to Apple Health.  I discovered that these do not sync directly to the Sense but use the Fitbit App.  I gave up my privacy twice.  These apps now have my sign-in info to Fitbit. I deleted the apps from my iPhone.  I will change my password shortly after this message.

I agree completely with your thoughts about fitbit. It is their issue. I
tried every single troubleshooting procedure possible 100s of times over
the past 6 months and none have worked for any length of time. Like I said
this one has worked for 1 day in a row. I don't expect it to last. I was
just passing it along just in case. I still consider my fibit sense to be
an ugly expensive watch.

If there is a new version of the app it’s not been released in AU. I’ve done all the things suggested, with no consistent luck. Now & again it will sync across all data points, but then forgets it managed to update, drops off the last bit of today’s data and refuses to sync again. Rinse & repeat. 

I am frustrated as I otherwise like my Sync & have had success with FitBit in general. I’ve resisted switching to another brand but this is getting ridiculous. 

[roblharding]

According to an earlier post from another user, the fitbit app was
updated so I tried their suggestion of deleting the app and
re-downloading it. It worked completely and quickly at least for the 1 day
that I have used it. I am hesitant to be optimistic because of all the
problems that I have had with the app. I have the same issues you have had
for 6 months now but the last 2 weeks have been much much worse.

[rjwilley52]

The app version I have now is Fitbit 3.41.1 (1050).  This app seems different from the previous ones. 

[rjwilley52]

I should add that you see this by pressing the lefthand upper circle, select Help & Support midway down, version number appears, Fitbit 3.41.1 (1050)

[roblharding]

That's the version I downloaded and it has now 2 count em, 2 days in a row.
I guess this is an updated version but I'm not sure. Fitbit never puts out
any info on products. The only communication that I get from them is
advertising trying to sell me something. That would seem to be a poor long
term business strategy.

[Mooselette]

I’m on that version (3.41.1), have been for a bit and still having issues. Won’t save the last 5kish steps from yesterday despite the fact they were there on the app when I went to bed. Won’t sync my exercise this morning or sleep last night but has most of (but not all) my steps so far today. 

[roblharding]

Since my app has worked for only 2 days in a row, I guess I have that to
look forward to in the coming days. None of us should have to pay the
amount we pay for fitbit and have to be constantly pessimistic but that is
the situation we are in at the moment.

Hi everyone.

Thanks for getting back with the requested information, as well for sharing your thoughts about this situation. I'm sorry you've gone through this experience. Because your watches are still not syncing correctly, I've forwarded all your details to our team and it seems they'll release a new Fitbit app version for iOS devices. Please wait and download it as soon as you see it available in the App Store of your phone.

If by any chance the issue persists after updating the Fitbit app, reply back to this thread so I can keep our team informed of this situation. I truly appreciate your patience and rest assured your feedback won't be taken for granted.

See you around.
