I have been using Garmin FR935 for a year - just connected to Strava to sync. Last 3 months on Garmin Connect now appear on Strava, and new activities seem to sync fine.
Is there any way to sync past Garmin activities (older than 3 months) to Strava?
Tried https://www.fitnesssyncer.com and also https://tapiriik.com/# which were recommended on various forums - but nothing seems able to sync activities older than 3 months...
Thoughts or suggestions on how to migrate the distant past??
