I've had my Venu 2s for about 2 years. Over the past couple of weeks it has been turning itself off when I pressed the button to stop an activity. When I plugged it back in it would allow me to save the activity.
Now it has started randomly turning itself off in the middle of an activity.
I've read other posts on the Garmin forum and it seems to have maybe been caused by a software update and there doesn't seem to be a solution to it.
