I recently bought my first ever smart watch a fenix 7 pro. I just had a poor night of sleep and my training readiness and body battery was poor. Decided to go for a nap. Ended up on 2hr. But my watch didnt recognize the nap and my tr and bb was exactly the same. Do you need to automatically start the nap function? What happens if you fall asleep without starting nap? I would think that would mess up the training readiness for some time? I also had a morning where i slept for 6 hrs opend my morning report but i was sick that day so i went to bed for another 5 and on my sleep history garmin only added that last 5 hrs.
