Yes. My food and exercise would not sync when I added the entries on my cell (Android) but would sync ok other way round. I deleted the MFP app on my phone. Downloaded and reinstalled again. Turned the phone off and on and the problem went away.
Ignore my response above. I had problem syncing from MFP on my cell phone and not from Fitbit. Tried to delete my comments and it would not let me. Sorry.
