FitBit syncing question

Options
Hi,

I just purchased a Fitbit and have it syncing with MFP. Yesterday, it did post my steps and added the additional calories to my food tracker.

Today, although my calorie intake listed in MFP has synced back to the FitBit, the steps showing in the Fitbit are not syncing back to MFP.

Can anyone help me to get this to work? I've searched previous threads, but nothing mentioned in them seems to be helping.
