While searching the forum I didn't see anything newer than 3 months...
I have been experiencing what seem to be random reboots/crashes on my 970. When I take a look at my body batter I can see periods where there has been no data collected throughout the night. I have also look down at my watch to check the time and the watch is in the middle of a reboot cycle. Yesterday I say it happen in real time when I when to select the walk activity. As soon as I clicked walk the watch crashed and rebooted.
I have been trying but I cant replicate it on demand.
