Historical data lost after updating app.

[gewmom]

My iOS app updated yesterday. When I synced this morning all my data to the date I bought my Blaze was gone. Weight, steps, sleep, everything was gone. Data from my Charge is there but nothing past January 18, 2016. Help! It made me set up the Blaze as new. I see the announcement for firmware update. I’m still on 402. What do I need to do?

Hello @gewmom, have a warm welcome to the Fitbit Community, 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. Please remember that all the information synced to the Fitbit app gets stored in our servers and none of it 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.

How do you fix your email account if you typed an error? All the options that I can see are resend to email. But if my email account given was not correct, I can not go find the emails. Please help! Also how can you get back to just using the original email account? Something happened to my fitbit and it was not registering information so I resync to another account to get data to show again this is why I am having problems.

I have never used another email address. I have all my data from using the Charge more than two years ago, but all my blaze data is gone since the app updated and logged me off.

Hello @gewmom, I hope you're doing well, thanks for taking the time to reply. It's nice to have you on board the Fitbit Community @Jaimer98, welcome! 

@gewmom, thanks again for your patience and working through these troubleshooting steps. I’ve reached the limits of what I can do for you here on the public community forums, so I've contacted our Support team on your behalf to look into this issue further and provide you with some options. Please keep an eye on your email inbox for further instructions. 

@Jaimer98, are you able to log in to your account (the one with the typo)? If so, go to your personal settings and change the email address on your account for a new one. Once you save the changes on your account, you will be asked to verify the new email address. 

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