I am quite unhappy to report multiple crashes during activitys like swimmin, triathlon, running, heart rate broadcasting, etc.
Often it happens when I want to use some features which are not in the top level menu like route back to start or changing the activity in a multisport race.
These features are one of the key ones I wantet to use in this watch an seeing the watch repeatedly crash make me quit upset.
My device is on the newest firmware and i resatrtet it and loaded a backup too.
Hope you finde a fix.
