Wondering if anyone had this happen to them before? I started my Bike activity on the Enduro doing a 70-km ride. Approximately at the 6.5km mark the watch killed the activity and returned to the watch face. Realizing this, I quickly restarted the activity and got the rest of the journey recorded without any issue. Glad this happened at 6.5km not 65km — scary stuff. Watch doesn't run any watch faces or apps from Connect IQ.
