BUG! The nap end alarm could not be stopped by any means if the screen was initially covered with your palm during the alarm.

Can you provide more details on how to replicate this issue?  I just added the Nap glance, started a nap, palmed the screen to blank it, waited for it to be over and start alerting and clicking the upper right button shut it down as I would expect.  Not sayingyou don't have the problem, I just couldn't replicate on my watch just now based on what you have in your post. 

When nap is over and alarm started don’t push buttons just palmed screen as a result you’ll see watch face but alarm sound continues 

What I understood using the palm on the screen (touch unlocked) is to get back to the home screen .  It's a quick way to get back to home screen if you are in sub-menu screen.   It works the same as Samsung watch.   I do not think if stops any action. 

if you using palm on the screen during simple alarm - it stopped alarm. But during nap-alarm same action leads to sound could not be stopped by any way and only turn off watch helped

I have fenix 8 47 amoled if this information could help

I have the same.  I'll try the nap-alarm and see.
