Week ending 2/6 total points 387. Won a Group Challenge total points 386 completed “Step into February” Challenge total back to 387. Lost a Garmin Challenge. Is that why points were taken away from me?
No, you will never lose points that way. The only way to lose points is that if you lose a badge. You can get the badge back by editing the activity that awarded you the badge. You just need to find out which badge it was.
