I recorded an indoor swimming activity with the wrong pool lenght, 50m instead of 25m. I have edited the activity in Garmin Connect "succesfully", but when I download the edited activity with the correct swim lenght (half of what it was recorded originally) it still shows the original settings. When I upload it to Strava it still displays the wrong lenght.
How can I modify an activity in the way that the file is also modified and I can upload it to Strava with the changes?
