Works perfectly for me. Do you definitely have MPF and GC connected? In MFP, go to "Apps" and see if GC is listed there? Maybe the connection between the two needs to be reset. Disconnect the services, close the page/app and open it again to check that it's definitely not there, then reconnect the two services. That day's details should then sync across (weight/calories/what ever you sync between the two) and it should work from that point on.
Do you happen to know if there is a way to have your calories displayed in garmin connect from MFP without the active calories being added to the total? I already have my goal in MFP set to take into account activity.
