Polar Flow wrong data sync
I use the Polar M600 for running. It syncs with Polar Flow and than, automatically to Strava. My activity details show correctly at Polar Flow, but when they get to Strava, for some reason they are messed up.I always seem to be faster at Strava, with some unreal spilts! For example, on my last activity I had a 1km lap at 5:00 (correctly shown on Polar Flow) but Strava insists it was at 4:35.
Does anyone have an idea how this is possible, as the data source is the same? I already tried to download a .TCX or .GPX from Polar Flow and manually upload to Strava with no success - the unaccurate splits keep appearing on Strava.
Any ideas on how to fix this?
