I have just bought a Venu 2 and have 4 years worth of Fitbit data I would like to import.
I can see on this forum of issues a few years ago but nothing recently
I have managed to import Body data but every time I try either Activities or Sleep I get this error message- An error occurred with your upload. Please try again.
I am assuming Fitbit has changed the export format so what I need to know is the exact format Garmin expects. That way I can look to modify the Fitbit output. Body data isn't that important, it is the activities I really want loading
