If not, any alternative ways to sync them automatically?
I prefer the layout and cleaner UI on POLAR Flow when compare to Garmin Connect. But the Garmin watches works better for me overall.
just noticed there isn’t a Polar forum. Will see if the support there can answer my question.
welcome any input from other Garmin users as well.
[update] got a verification from Polar Twitter. They said the Strava <-> Polar Flow link is just one way, Polar flow feed data to Strava
