in the past I have been using map my rum. lately I purchase a new gramin and want to use the gramin connect app to monitor my activity.
I want to import to gramin connect all my past activity with MMR but so far no luck. I exported to CSV and tried to upload but there seems to be some kind of unclear error, I tried using FitnessSyncer but it doesn't support garmin as desitnation anymore.
anyone who has a clue is welcomed to share
