Manual nap function has always been flaky and unreliable on my FR970, regardless of firmware rev. (I'm writing this while on 16.28.)
E.g., I set nap timer, confirm it, it says "enjoy your nap", I take a nap ... and typically: nothing happens. I wake up late and the watch has completely flaked out: no nap event, no alarm after the timer ostensibly ran out. Nothing. It's like it forgot it was in a nap (during my manually started nap).
Furthermore, since the supposed nap detection was introduced, no detection ever happens. I meet all the criteria: time after/before sleep, stillness, actually napping (!). Detection has never worked once.
When will GARMIN repair this?
Thank you.
