I completed 60 minutes of yoga but I did not get the June Wind Down badge and it clearly shows I've done more than 60 mins but when I go into the Wind Down challenge it says I've done 0mins.
Thanks
You must log your yoga with a Garmin device to make it count for the challenge. Manually created activities do not count.
Also make sure that you used the correct activity type. It must say Yoga in Garmin Connect.
