Hi All.
My 935 has been pretty rock solid for over the year I've had it, except for lately.
Once a week, I do boxing at my work, for around 45 mins sessions, which is pad work not sparing.
I wear the HRM strap on my chest and place the watch on my left ankle, activate Cardio and lock it.
Seems to work fine when I check it (around 15 mins in) but at the end of the session the Cardio app is no longer running and is back at the time screen.
Sometimes it will save what it has recorded before quitting out, sometimes nothing.
Anyone seen this, or can explain why it would keep on quitting?
Thought I would ask here first before logging a support request.
Cheers
