Please read below, I added brackets "[ ]" to what I added to Fitbit's suggested remedy as this is what worked for me and I used existing email and did not lose any data!
For us to help you with this, kindly disconnect and reconnect FitStar and Fitbit by going to app.fitstar.com and logging into your account.
To relink the account you created by registering with Fitbit and link it to your main account, complete these steps:
1. Go to app.fitstar.com and log in to your FitStar account with the option to login with Fitbit.
2. Click the menu icon in the top right corner, and choose Settings.
3. Click "Email and Password" and add an email address and password to your account.
[Or if you already have an email address entered just leave it]
Please note that the email address you use must be different from any other email address you've used for an existing FitStar account.
[Not true in my case as I only have one email address and I had already previously entered it when logging in through Fitbit and left this email address here and just did all the above and then logged in through Fitstar instead of through Fitbit. It did not seem to be immediate in working; however I know the very next evening I did 4 workouts and all of them synced and logged to Fitbit.]
4. Next, click "Services" and disconnect Fitbit.
In addition to that, please be advise that disconnecting and reconnecting will not sync their past history but should insure that any future sessions sync correctly.
[This is not true either; if you keep your existing email address as I did you keep all your existing data! Yay! Awesome!]
You'll now be able to link your main FitStar account to your Fitbit. Let us know if you have any further questions.
[Thank you Fitstar for sticking with me on this issue!]
