Second night using my watch... My sleep tracking has been way off. Last night for example I have a 1+ hour block of "awake" around 2am.. Which did not happen. I feel like I had a great sleep and feel refreshed and my BB recovery was awful. My previous fitbit was much better at tracking sleep, which sucks cause I thought this watch was an upgrade from that. I am wondering if the watch takes time to adapt like some other metrics?
