Hi guys,
I used the Whoop 4.0 for 18 months, and switched to the 5.0 8 weeks ago and everything works fine so far, but it won‘t track naps at all. Tried an Amazfit Balance 2 and an Ultrahuman ring today and both tracked a longer nap quite good, while the Whoop 5.0 completely missed it.
Same experience. My Oura Ring always detects a nap while Whoop 5.0 never does.
The only nap it has detected never happened. I was teaching school–it was a study hall–but trust me, I never went to sleep with 13 high schoolers in the room!
