Firstly, I apologise if this has been raised before but I have searched through here and the Fenix 5 forum without finding anything.
I've only had the 935 for a couple of weeks having upgraded from the 910.
On my last couple of swims my watch has been recording normally for most of the session but then seems to take it upon itself to record intervals as "rest", this has happened towards the end of the workout admittedly but neither one has been particularly long. Am I accidentally pressing one of the buttons or something which is causing this to happen? I am definitely not in the Drill Log.
