instinct toggling between modes on its own

Hi,

My instinct has started to toggle between modes on its own. Returns to normal once I press the "set key, yet starts all over again at an unpredictable frequency. This has started happening a couple days ago, following a new software upgrade.

Last 4 Hours Heart rate - Notifications Screen - A Direction Arrow - Some weird time zone - the Climb Activity recorder - Compass - Toggle Modes Screen - Last 4 Hours Heart rate and so on...

I may have accidentally made a set-up change yet I doubt it.

Anyone have an idea?

Thanks,
