The last 3 nights mine has been messed up. I go to bed around 10pm and wake up at 530am. Every night I also get woken up around 4am as well, I always check my data at that time as well. The first night at 4am it showed 141 and at 5am it went to 64. The next night it showed 0 both times. Today at 4 it showed 37 and then again at 5am it showed 0?. When I click to see it on the graph it shows no data for the last 2 days. It picks up everything else(with exception of breath rate it's finicky on that one all the time). I know FB isn't a medical device but I got it on my Drs advice to help my medical anxiety altho the last 3 days have wreaked havoc on that. I've turned the watch off, I've re synced it to the phone. I've also noticed the heart rate and the real time graph on the watch are not adding up.
