My Sense watch doesn't show sleep time

[SunsetRunner]

My Sense shows 0 hours and 0 mins of sleep. The app shows I slept 6 hours and 48 minutes but it doesn't appear on my Sense. It is synced and I have tried shutting down the watch. This is the second day of this happening

Please verify its not a watch face issue, by

On the watch

Swipe left 

till you find the Today app

Click it

Scroll down to Sleep information

if its - -  click it so it shows last data

If it is correct it is a clock face issue

Your watch must have synced recently

Sometimes because of server load, it takes a few minutes and a second sync to get sleep on the tracker. I a read reports that it has taken hours but I haven't experienced this..
