Not sure I did anything special, have had the watch over a year and on the latest firmware. Both times I woke up and in the Garmin Connect Mobile app on iOS, noticed that my steps were already at a few thousand but not moving. Heart rate widget was not showing any maximum and on clicking it said no data for today. Went to the watch, on swiping to an activity widget it had a message saying tap to activate activity tracking. Once I did that it started tracking with the step count starting from 0, looks like it lost all the previous data from whenever it stopped tracking.
Anyone else had the same issue recently?
Thanks.
