One of my iPhones doesn't show my info.

I have exact same account on both iPhones but on one iPhone it won’t show all my info like friends etc?  Why is this and how do I fix I?  They are both synced

Hello @SunsetRunner, I hope you're doing well, thanks for joining the Fitbit Community. 

I appreciate you have brought this to my attention. Tell me, have you updated the app in both of your iPhones? If so, it's possible the app is not showing the information already stored in our servers in one of your phones, as it's possible to see it on the other one. In this case I would like to suggest you the following:

• Force-quit the app on the phone you're not able to see the information. If this doesn't seem to work:
• Log out from the account, restart your phone and log back in. 

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