Ability to change watch face completely disappeared

Hi,

I recently got a Garmin Fenix S6 Sapphire and after charging it for the second time ever, the ability to change the watch face has completely disappeared.  It is now not possible to change the face from the basic digital display.  The menu button on the watch does not offer 'watch faces' as an option at all.  Please advise how to best rectify this as the watch is less than 5 days old.  Thank you.
