We made some improvements in the sleep/nap tracking feature on this watch with the latest update. Please ensure that your watch is up to date on the most recent sofware version 9.24. If this persists, after this update, please reach out to your local Garmin Support team to investigate this further.
I have the lastest version 9.24 on my Venu 3s,and I have just bought the watch. Both during this weekend and today it recorded naps when I was sitting up reading a book.
So I agree, I would really like to be able to delete naps or as suggested be able to change it to a restful period since the wrong naps affect the sleep information.
Thanks, these are great suggestions and I highly suggest submitting them here: Garmin Ideas
