When resting my heart rate is much higher than it really is, and I've confirmed this by checking my pulse manually and then comparing to the fitbit. I have restarted it and it still has this issue. The green lights are flashing. I also had an issue when I took a shower today, it showed my heart rate ~150 bpm the whole time I was showering and counted my shower as exercise. It is also documenting that I am asleep when I am not. This whole afternoon it says I was in a deep sleep when I actually wore the watch while I ran errands. It then says I woke up and now says I just woke up from a deep sleep, when I was just at dinner.
