Hi @JDalg your Sense doesn't store weight or sync with MFP.
It is your MFP account that should sync with your Fitbit account.
As with any third party sync issue. The only option we have is to revoke access and reconnect the apps.
If this does not work, the next step is to contact the third party, in this case it would be MFP.
See How do I manage app access
I've also moved your post to the Third Party Board.
