Historical data lost after updating to iOS11

[Aggletooth]

After the last update, I lost all the historical data of my previous workouts in the app. Since the ios11 update, my Fitbit charge 2 was having issues connecting. I’ve mow updated to the most recent versions of the app and updates the tracker. Now all my historical heart rate data is gone and hasn’t recorded my heart rate since the update. It still shows up in “real time”, it’s just not being saved. All the historical data is there when I go to Fitbit.com dashboard. And, for what it’s worth, I have to pull the screen down to see who’s #1 in my circle of friends. It doesn’t stay on the screen. Overall, the last couple of updates have been super buggy.

Hello @Aggletooth, is nice to see you around, I hope you're having a great day.

This seems like a very odd situation; however in this case I would like to suggest you to try the following in the Fitbit app as you mentioned all the information is still showing in your online Dashboard:

• Force-close the app by double tapping the home button on your phone and swiping up the app. If this doesn't seem to work after a few tries:
• Log out from the app, restart your phone and log back in. 

Now, the issue you're mentioning about your Friend list, this is a situation affecting some users and I have already forwarded the information to our team. Once I have more information to share about this situation, I'll make sure to update the thread and let you know.

I hope this can be helpful, give it a try and keep me posted in case you need anything else.

It’s actually not updating on the online dashboard either. I assumed it was since it was the day before. I went to check last night and it says it hasn’t synced since the update.

I have the same problem. After iOS 11, app lost my Alta and all my data

I’m having the same problem. All of my data from feb-Oct is gone and it’s the same for my online dashboard

At this moment I will forward the information you have provided to our team so they can take a better look at this situation. Once I have more information to share with you about this issue I'll make sure to update the thread accordingly.

Lost historical data from most of 2015 and 2016 after the last update too.

Fitbit app made me re log in and had me do a email verification. Lost all my historical data? How do I get it back?

[RichardThomas]

Same with me. Bit annoying.

Lost all my historical data after upgrading to ios11 in late October, any ideas? Doesn't seem to be an answer to the problem yet...

Hello @Neilruk, @Janders9, @RichardThomas and @Grahamdking thanks for joining the conversation, it's great to have you on board. 

Have you logged in to the app recently after updating it or after being logged out? Is it possible you have a different Fitbit account registered to a different email address? We have received reports from people who have not been able to see their past data history but they have logged in with a different email (often containing a small typo) which might be your case as well as all the information gets stored in our servers and none of the information there is deleted. 

Please try to log in with another email address you might have and let me know if you're able to see the previous data you're not able to see right now. 

Thanks for your patience, if there's anything else I can do for you please feel free to reply.
