It feels like this is a common issue?
I am using a Renpho scale. I have connected that to MFP. So when I weigh myself Renpho updates my weight in MFP.
I have synced my Garmin and MFP. Syncs fine and Garmin pulls weight through from MFP. But only once. If I then disconnect and reconnect it pulls through the new weight but only once.
So in order for it to update my new weight I have to constantly disconnect and reconnect Garmin and MFP. I've resorted to manually entering the weight - which defeats the object!!
